Practice in a group of 3 or less - Solve Word ProblemsSolve Word Problems On #3, change the -3 to a positive 3.

Answers 1. a) x + 3 ≤ 15 b) 5x + 2x ≥ 70 c) n - 15 < C = 3S so 3s + s ≤ 160 so the maximum weight Carol can be is 120 pounds, Sue can be a maximum weight of 40 pounds 3. n ÷ 3 ≤ 15 so n ≤ x ≤ so x ≤ x ≤ so x ≤ 7.64
