Explain the five steps for solving rational equations. Can any of these steps be eliminated? Can the order of these steps be changed? Would you add any steps to make rational equations easier to complete or understand? - Find the LCD of the terms in the equation. - Multiply each side of the equation by the LCD. - Simplify each term. - Solve the resulting equation. - Check each answer in the given equation. Any value that makes a denominator equal 0 should be rejected because it is an extraneous

designed for students in beginning Algebra classes. It is an introduction to the basic functions of algebra including the definition of an equation, using basic mathematical skills to solve equations, and applying equations to problem solving. South Carolina Standard 8-3: Through the process standards students will demonstrate an understanding of equations, inequalities, and linear functions (South Carolina Department of Education, 2007). Specific Indicators as outlined by the South Carolina Department

Chapter 15 1. Write the expressions for Kc for the following reactions a. 2 O3(g) 3 O2(g) b. Ti(s) + 2 Cl2(g) TiCl (l) c. 4 HCl(aq) + O2(g) 2 H2O (l) + 2 Cl2(g) 2. If Kc = 0.042 for PCl3(g) + Cl2 (g) PCl5(g) at 500 K, what is the value of Kp for this reaction at this temperature? 3. At 1000 K, Kp = 1.85 for this reaction: SO2(g) + ½ O2(g) SO3(g) a) What is the value of Kp for the reaction SO3(g) SO2(g) + ½ O2(g) b) What

Cold Equations Everybody must deal with "Cold Equations" in his or her life. Whether it is death, heartbreak, having to go to school, crime, violence, family, all of us must come to grips with things we can't change. The author from this novel "Cold Equations" is trying to teach us that nature is unforgiving and no one can avoid it. Death is a cruel part of law of nature, it can take away someone's life and won't care about it. Everybody has to deal with the laws of nature, sometime in their

Lubrication- Theoretical Modeling Thin-Film Lubrication (TFL) deals with the region wherein the film gap is in the molecular scale. Due to this small scale, researchers rely on molecular dynamic simulation which has the given macroscopic flow of equations in which the experimental approach of this study depends. However, seeing the study in theoretical view is still limited. This viewpoint considers the material to be a continuum one in an ensemble-averaged, rather than a spatial-averaged. For a

the triangle, and “a” and “b” are the other two sides of the triangle. In a right triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides. We let a = x, and b = 2x + 4, so that c = 2x + 6. Then we begin the equation: x^2 + (2x + 4)^2 = (2x + 6)^2 | The binomials are placed into the Pythagorean Theorem. | x^2 + 4x^2 + 16x + 16 = 4x^2 + 24x + 36 | The binomials are squared | -4x^2

represented by the equation Ad(t)=7.53(1.041)t. The total amount of money in Tuckers account is represented by the equation At(t)= 10.42+ 0.53t. The purpose of this assignment is to use mathematical equations and calculations, as well as tables and graphs to compare the total amounts of money in each account and determine when the savings accounts will be equal and when one account will become larger than the other. The first step is to write out the equations as well as
