Question

What is the solution set of this inequality?

8(x-5)- 3x ≥ -20

A. x < -12
B. x ≥-3
C. x ≥ 4
D. x ≤ 12

Answer 1

We have:

8(x-5)-3x >= -20

8x-40-3x >= -20

5x >= 20

x >= 4

Therefore, the answer is C.

Answer 2

• C. x ≥ 4

--------------------------

Solve inequality in steps

• 8(x - 5) - 3x ≥ - 20
• 8x - 40 - 3x ≥ - 20
• 5x - 40 ≥ - 20
• 5x ≥ - 20 + 40
• 5x ≥ 20
• x ≥ 20/5
• x ≥ 4

Option C is correct.
