QLT1 Task 5 A. Create a story problem using one of the above real-world scenarios as a basis, including realistic numeric values, by doing the following: 1. Describe the real-world problem. I was looking into phone plans and stumbled upon T-Mobile, and I decided that I needed a cell-phone and took a look at the plans. T-mobile had one plan that was 50 dollars a month and is unlimited talk, text and web, T-Mobile also has a plan for 30 dollars a month for 1,500 talk and text minutes. After

in the four (4) algebraic processes. Outline each procedure in the process of solving algebraic equations and then try to use your outline as a guide to teach a follow student. •The author of your textbook indicates, “If you add percents, you often obtain incorrect results.” Explain in your own words what kinds of errors contribute to inaccurate percent results. •Determine what makes solving an equation with two (2) variables different than one (1) variable.

Systems of Linear Equations in Three Variables Answer the following questions to complete this lab. Show all of your work for each question to get full credit. 1. Solve the following system of equations: a. x –2y+z=6 b. 2x+y –3z= –3 c. x –3y+3z=10 Add equation b and c: 2X+Y-3Z=-3 +X +3Y+3Z=10= 3X-2Y=7 Add equation a and c, attempting to cancel out variable c. (multiply equation a by -3. -3(x-2Y+Z=6): -3X+6Y-3Z=-18 + X-3Y+3Z=10 = -2X+3Y=-8 Add the new equations together to

indicates that to find the treasure, one must get to Castle Rock, walk x paces to the north, and then walk 2x + 4 paces to the east. If they share their information, then they can find x and save a lot of digging. What is x? We need to look at the equation so we can know how far Ahmed will have to walk, which is 2x+6 paces from Castle Rock. Even though Vanessa’s half of the map does not indicate in which direction the 2x + 4 paces should go, it can be assumed that her’s and Ahmed’s paces should end

system of equations in w, x, y, and z. For Intersection I1: Because 5+10=15 cars enter and w+z cars leave the intersection I1, then w+z=15. For Intersection I2: Because w+x cars enter the intersection and 10+20=30 cars leave, then w+x=30. For Intersection I3: Because 15+30=45 cars enter the intersection and x+y cars leave, then x+y=45. For Intersection I4: Because y+z cars enter the intersection and 10+20=30 cars leave. traffic will keep flowing if y+z=30. Arrange the equations where the
