Final answer:
The solution to the inequality 3t < –15 is t < –5, attained by dividing both sides by 3.
Step-by-step explanation:
The student's question involves solving an inequality, specifically 3t < –15. To solve for t, we need to isolate t on one side of the inequality. This can be done by dividing both sides of the inequality by 3. The solution to the inequality is:
- Divide both sides by 3: t < –5
Therefore, the correct answer to the inequality 3t < –15 is t < –5. The other options such as t > –5, t < –45, and t > –45 are incorrect.
