Answer:
t ≤ -3
Explanation:
5t ≤ -15
You are solving for t. That means you want t alone on the left side. t is being multiplied by 5. To get rid of a multiplication by 5, you do the opposite operation, and you divide by 5. You must do the same operation to both sides of an inequality, so you must divide both sides by 5.
5t/5 ≤ -15/5
t ≤ -3
