9. 5. You start with $20 and save $6 each week. 20 + 6xx = # of weeks 6. You have $150, but are spending $2 each day. 150 – 2x x = # of days

10.  Evaluate – substitute a number for each variable in an algebraic expression and simplify using the order of operations. Solve.  Order of Operations ◦ Parentheses ◦ Exponents ◦ Multiply/Divide (left to right) ◦ Add/Subtract (left to right)

11. 7. 7(a + 4) + 3b – 8 for a = –4, b = 5 = 7(–4 + 4) + 3(5) – 8 = 7(0) + (3)5 – 8 = 0 + 15 – 8 = 15 – 8 = 7
