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

  4. Question # 3 • Solve for x: Axyπ = BC • Answer:x = BC/Ayπ

  5. 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.

  6. Question #5 • Solve and Graph on a number line the following inequality5x – 7 ≥ 8 • Answer: x ≥ 3Graph on Board

  7. 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.
