Module 1 TEST REVIEW

Question #1  If Eddy wants to have a party and invite all his friends, it is going to cost him $150 to cater the party, plus $4 per person for drinks. If he only has $350 to spend, how many people can he invite to his party?  Equation: 4x = 350  Answer 50 people.

Question # 2  Solve and Justify: 5p – 12(3p + 2) = 51  Step 1: 5p – 36p- 24 = 51Distribute  Step 2: -31p = 75Combine Like Terms & Add POE / Add Inverse  Step 3: p = -75/31Division POE/Mult. Inverse

Question # 3  Solve for x: Axyπ = BC  Answer: x = BC/Ayπ

Question #4  Wes likes to buy wings and a coke for the big game each Sunday and the wings cost $8/ dozen(only sold in dozens, not individually) and the coke costs $2, write an inequality expressing the fact that Wes can only spend $36 on his meal.  Answer: 8x + 2 ≤ 36  How many wings can he buy?  Answer: 4 dozen or 48 wings  Is 3 dozen wings a solution to the inequality?  Answer: Yes, Wes could buy 3 dozen wings and still be under budget.

Question #5  Solve and Graph on a number line the following inequality 5x – 7 ≥ 8  Answer: x ≥ 3 Graph on Board

Question #6  If x = y, is ax = ay? Explain why or why not.  Answer: Yes, they are equal because if x = y, then if you multiply them by the same number they will always be equal.

Question #7  Graph the following equation y = 3/2x + 5  Answer:

Given the pattern below, answer the following questions  1. How many tiles will be in the 5 th stage?  Answer: 9  2. Write an equation that will be able to determine the number of tiles in any stage.  Answer: 2x – 1  3. How many tiles would be in the 25 th stage?  Answer: 49

Use the following table of symbols to answer the questions  Explain the meaning of C x A.  Answer: Total cost of mowing per week.  Write an inequality expressing that the weekly income from mowing must be more than the total cost of mowing per week.  Answer: C x A < I  Write an inequality expressing that if a worker makes $30 per acre mowed, plus $10 flat fee he will have more than $500.  Answer: 30A + 10 > 500  How many (whole) acres will he have to mow to earn more than $500?  Answer: 17 acres.
