Which is the answer A- D ?
Brilliant_brown [7]

Answer:

  • B.

Step-by-step explanation:

Inequality:

  • -3b - 15 > -24

The dot must start at -3 (-3b).

Which would be B.

Then, we solve this inequality:

  • -3b - 15.

Solve:

  • -3b - 15
  • = 18b
  • 18b > -24.
<h2>Hence, the answer is B.</h2>
