Question

The temperature this morning was only 7 degrees. By noon, the temperature had risen 4 degrees. But by midnight, it had dropped 9 degrees. What was the actual temperature at midnight?

Answer 1

The actual temperature at midnight was 2 degrees.

Step-by-step explanation:

The temperature at midnight can be calculated by adding the rise in temperature from morning to noon and subtracting the drop in temperature from noon to midnight from the morning temperature.

So, the temperature at midnight would be 7 degrees + 4 degrees - 9 degrees = 2 degrees. Therefore, the actual temperature at midnight was 2 degrees.
