We have:

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

8x-40-3x >= -20

5x >= 20

x >= 4

Therefore, the answer is C.

Answer:

  • 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.
