Question

Please answer this question, the answer to Part A is 100≤20x≤1,000, use that to help you with this question

Answer 1

5 ≤ x ≤ 50

Explanation:

The goal is to isolate x

100≤20x≤1,000

(100≤20x≤1,000)/20 = ==> divide the entire inequality by 20 to remove the

20 in front of the x in '20x'.

100/20 ≤ 20x/20 ≤ 1,000/20 ==> Hence, you divide each term by 20

5 ≤ x ≤ 50 ==> simplify each expression in the inequality
