submit question

Explanation:

Step1: Divide both sides by -9

To solve for \( t \) in the equation \( -9t = 72 \), we divide both sides of the equation by \( -9 \). This is because we want to isolate \( t \), and since \( t \) is multiplied by \( -9 \), dividing by \( -9 \) will reverse that operation. The equation becomes:
\[
t=\frac{72}{-9}
\]

Step2: Calculate the result

Now we calculate the value of \( \frac{72}{-9} \). We know that \( 72\div9 = 8 \), and since one of the numbers is negative, the result will be negative. So, \( \frac{72}{-9}=-8 \).

Answer:

\( t = -8 \)
