...Distributive Property Kimberly Smith MAT 221 Introductions to Algebra Instructor: Andrew Halverson February 15,2014 I will be using distributive property to solve how properties of real numbers are used while I simplified the three given expression. To solve these three math problem I will use the distributive property to remove the parentheses in the problem. I will also combine like terms by adding coefficients and add or subtract when needed. Finally I would have my answer and then decide if the answer is simplified, if not I will simplify. The solving of properties of real number the properties of real numbers are important to know in all subjects, even complex numbers, because many of the properties are shared. Additionally the argument to any equation in algebra is real; therefore, algebraic expressions only manipulate reals (that is, if you have integer coefficients and no radicals). 1. 2a(a-5)+4(a-5) = The given expression 2a^2-10a+4a-20 = I will use the distributive property to remove parentheses so I can combine like terms by adding coefficient. 2a^2-6a-20 = Is simplified no combine like terms by adding coefficients 2a^2-6a-20 = Answer 2. 2w – 3 + 3(w – 4) – 5(w – 6)= The given expression 2w - 3 + 3(w - 4) - 5(w - 6) = Distributive property removes parentheses 2w - 3 + 3w - 12 - 5w + 30 = Combine like terms 2w + 3w - 5w - 3 -12 + 30 = Combine like terms by adding coefficients and add and subtract to get sum.

...called like terms because they contain the same letter. Like terms can be added together – this is called collecting like terms. Instead of writing 2m ϩ 3m ϩ b ϩ 2b, we can write 5m ϩ 3b or 3b ϩ 5m. We cannot combine 5m and 3b in any simpler way than this because m and b are not like terms – they stand in for different unknown numbers. We can multiply two or more unknowns together. a ϫ b is written as ab. b ϫ a is the same as a ϫ b and is also written as ab. Instead of writing 2a ϩ 3b ϩ 3ab ϩ ba, we can write 2a ϩ 3b ϩ 4ab. We can add 3ab to ba to make 4ab because ab and ba are like terms.

...Simplifying Expressions Christy Bailey MATT 221: Introduction to Algebra Instructor: Stacie Williams October 13, 2013 Simplifying Expression Include in this paper I have demonstrated the following solutions for the three problems listed below. Using th given vocabulary words I have broken down each problem using the proper steps in solving the algebraic expressions. Also shown will be what is important about real numbers and in what way they are useful in using real numbers in solving algebraic expressions. By breaking down the equation you can simplify the equation down to lowest terms. Gathering the like terms in the equation is a step in breaking down the expression correctly. Take the coefficient and multiply it by the variable. The distributive property in the expression is the letters in the expression. When solving a algebraic expression you always remove the parenthesis first. A.)2a(-5 + a) + 4(a + -5) Simplify the terms (-5 * 2a + a * 2a) + 4(a + -5) (-10a + 2a2) + 4(a + -5) -10a + 2a2 + 4(-5 + a) Reorder the terms -10a + 2a2 + (-5 * 4 + a * 4) -10a + 2a2 + (-20 + 4a) -10a + 4a = -6a -20 + -6a + 2a2 Combine the like terms : -20 + -6a + 2a2 a = 5 This is...

...Jennifer Dominguez MAT221: Introduction to Algebra (ACP1424E) Instructor: Calandra Bean Assignment week 1 June 16,2014 P.1 · 2a(a – 5) + 4(a – 5) First I would start by simplifying the equation with multiplying 2a to the numbers within the parenthesis. So it would be 2a times, a which would be 2a squared because you would put a one in front of the a in the parenthesis. Then you would multiply 2a times five, which would be -10a. Then you would multiply four times (a) which would be 4a then you would multiply four times negative five which would be negative twenty. So the new equation without the parenthesis would be 2a^2-10a+4a-20 which would then be 2a ^2-6a-20 because you would subtract -10a from 4a. 2a^2-6a-20 this is the simplified form. · 2w – 3 + 3(w – 4) – 5(w – 6) First you would need to simplify the equation by multiply three times w then to the -4, which would be 3w-4, then you would multiply -5 by the w in the parenthesis then by -6 so you would have -5w+30. So when you have the equation it would be 2w-3+3w-12-5w+30 then you would start left to right with like terms. 2w +3w, which would be 5w-5w, which would be w then you, would do -3-12, which equals -15+30 which equals 15. Then the simplified equation would be w+15 P.2 · 0.05(0.3m + 35n) – 0.8(-0.09n – 22m) First you would multiply 0.05 by 0.3m which would be 0.015m, then you would multiply 0.05 by 35n which equals 1.75n.

...approximately equals amounts of what is being measured. Example: Grade Point Average B) A rank-order variable is numeric and the numbers stand only for the relative ranking. Example: A graduate standing in their class. Their GPA makes a big difference for instance if they stand first or second in the class. C) A nominal variable is not numeric and values are names or categories. Example: A nominal variable for gender would be female and male. D) A ratio scale is measured by equal-interval variable. An equal-interval variable has an absolute zero point on the ratio scale. An absolute zero point means there is an absence of the variable. Example: A number of cats an individual has. If one person has three and the other has six, you can say that they have three times the amount of that person. E) A continuous variable is a theory that you can have an infinite number between 2 variables. Example: An example of this would big age. You can say you are 12.5 years old. 15.

...DETAILED SOLUTIONS AND CONCEPTS - FORMULAS AND WORD PROBLEMS Prepared by Ingrid Stewart, Ph.D., College of Southern Nevada Please Send Questions and Comments to ingrid.stewart@csn.edu. Thank you! PLEASE NOTE THAT YOU CANNOT USE A CALCULATOR ON THE ACCUPLACER ELEMENTARY ALGEBRA TEST! YOU MUST BE ABLE TO DO THE FOLLOWING PROBLEMS WITHOUT A CALCULATOR! Formula rearrangement refers to isolating a letter term other than the one already isolated in the formula. Solving formulas in the manner often shortens our work when doing repeated formula evaluations. After we solve the formula for the desired variable, we rewrite the formula with the variable on the left side for convenience and for use in electronic spreadsheets. Problem 1: Solve the "mark up" formula M = S - C for S. To solve the equation above, we will use the Addition Axiom to isolate the variable S by "moving" all terms associated with S by addition away from the variable. The variable associated with S by addition is C. Therefore, we must add C to both sides of the equation. M+C=S-C+C and M + C = S Finally, we rewrite the formula with S on the left S=M+C Problem 2: Solve the interest formula I = PRT for R. It stands for Interest = Principal Time. Rate To solve the equation above, we will use the Multiplication Axiom to isolate the variable R by "moving" all terms associated with R by addition away from the variable. The variables associated by multiplication with R are P T or PT. Therefore...

...The Influence of Mathematics on Daily Social Activities MTH/110 March 2, 2015 The Influence of Mathematics Society is an important concept in which stands the intellectual development of mathematics and science. Today, in society, mathematics makes extraordinary demands and so to the world of mathematicians and scientists. The purpose of the report is to identify the influence and effects of mathematics in society. It includes some history of math and its major demands and capabilities that come with the material and mathematicians. Math Background People have believed in mathematics and the discipline that comes with it since centuries ago, some may like, and some may not. Some people used to worship mathematics and believe in it for living like Aryabatta and Bhaskara. Back to the 4th century, Aristotle and Plato had already an idea of the existence of mathematics in their mind and the external world; also he argued about a positive effect on individuals (Dossey). In the middle ages, mathematicians were coming out and at one point competing without knowing in discovering new techniques. Archimedes had one of the greatest impacts on its work in mathematics but he was known later in the 16th century when Federico Commandino in 1558 translation into Latin most of his printing texts and spread it out with other mathematicians and physics of the time, that includes Johannes Kepler and Galileo Galilei (Toomer, 2014). Many other mathematicians...

...is equivalent to the OR logic function, as well as parallel switch contacts. • Boolean multiplication is equivalent to the AND logic function, as well as series switch contacts. • Boolean complementation is equivalent to the NOT logic function, as well as normallyclosed relay contacts. 1 Boolean algebraic identities The algebraic identity of x + 0 = x tells us that anything (x) added to zero equals the original ”anything,” no matter what value that ”anything” (x) may be. Like ordinary algebra, Boolean algebra has its own unique identities based on the bivalent states of Boolean variables. The first Boolean identity is that the sum of anything and zero is the same as the original ”anything.” This identity is no different from its real-number algebraic equivalent: No matter what the value of A, the output will always be the same: when A=1, the output will also be 1; when A=0, the output will also be 0. The next identity is most definitely different from any seen in normal algebra. Here we discover that the sum of anything and one is one: Next, we examine the effect of adding A and A together, which is the same as connecting both inputs of an OR gate to each other and activating them with the same signal: Introducing the uniquely Boolean concept of complementation into an additive identity, we find an interesting effect. Since there must be one ”1” value between any variable and its complement, and since the sum of any Boolean quantity and 1 is 1, the sum of a variable...
