To solve the inequality \(-32.5 - 6b \geq 48.5\), we need to isolate \(b\). Here’s how we can do it step-by-step:
1. Start with the inequality:
\[
-32.5 - 6b \geq 48.5
\]
2. Add \(32.5\) to both sides:
\[
-6b \geq 48.5 + 32.5
\]
\[
-6b \geq 81
\]
3. Divide both sides by \(-6\). Remember that when you divide an inequality by a negative number, you must reverse the inequality sign:
\[
b \leq \frac{81}{-6}
\]
\[
b \leq -13.5
\]
This means \(b\) must be less than or equal to \(-13.5\). Among the provided options, \(−13.5\) is not included because the inequality is true for values less than or equal to \(-13.5\). Thus, the correct answer must be another value that is less than or equal to \(-13.5\).
The options provided are:
- −13.5
- −12.5
- −12
- −13
The value \( -13.5 \) itself makes the inequality a true statement, as \( -32.5 - 6(-13.5) = 81 \), which satisfies \( 81 \geq 48.5\).
So, the answer is **−13.5 (or negative 13.5)**.
