Warm Up Write the verbal expression. 5 ÷ b 8(x + 4) Write the algebraic expression . 3. Four increased by 9 4. The quotient of h and 10 5. The product of 6 and k. 6. 12 less than 20 Possible answers 55 divided by b 8 times the sum of x and 4 4 + 9 h ÷ 10 6k 20 - 12

Example 1: Evaluate the expression. 4x + 7 for x = 6 4(6) + 7 Replace the x with the 6 and then use order of operations to solve. 24 + 7 = 31

Example 2: Evaluate the expression. 5a + b for a = 4 and b =10 5(4) + 10 20 + 10 = 30

Example 3: Evaluate the expression. 4x + 5y – (9 – z) for x = 2, y = 4, and z = 7 4(2) + 5(4) – (9 – 7) 4(2) + 5(4) – (2) 8 + 5(4) – (2) 8 + 20 – 2 28 – 2 = 26
