Which of the following values for b makes the inequality −32.5−6b≥48.5 true?(1 point) Responses −12.5 negative 12.5 −13.5 negative 13.5 −13 negative 13 −12

1 answer

To solve the inequality \(-32.5 - 6b \geq 48.5\), we can start by isolating \(b\).

  1. Add \(32.5\) to both sides: \[ -6b \geq 48.5 + 32.5 \] \[ -6b \geq 81 \]

  2. Now, divide both sides by \(-6\). Remember that when you divide by a negative number, you need to flip the inequality sign: \[ b \leq \frac{81}{-6} \] \[ b \leq -13.5 \]

Now, we can compare the options you provided:

  • \( -12.5 \)
  • \( -13.5 \)
  • \( -13 \)
  • \( -12 \)

The values of \(b\) that satisfy the inequality \(b \leq -13.5\) are \(b = -13.5\) or any value less than \(-13.5\). Therefore, the value of \(b\) that makes the inequality true is:

−13.5 (negative 13.5)
