Question

Select the correct answer.

Which inequality represents all the solutions of -5x + 5 ≥ 160 − 10x?

Answer 1

x ≥ 31

Explanation:

-5x + 5 ≥ 160 − 10x

Add 10x to each side

-5x+10x + 5 ≥ 160 − 10x+10x

5x+5 ≥ 160

Subtract 5 from each side

5x+5-5 ≥ 160 − 5

5x ≥ 155

Divide by 5

5x/5 ≥ 155/5

x ≥ 31
