Question

Keith records the temperature outside every hour for 5 hours. He finds that the temperature dropped by the same amount each hour. After 5 hours, he finds that the temperature dropped a total of 15 degrees F. He writes this number sentence: ( -15) 5 = -3 What does the number sentence mean?

Answer 1

Explanation:

The number sentence (-15) 5 = -3 is not accurate and does not represent the situation correctly.

In the context of Keith recording the temperature outside every hour for 5 hours and finding that the temperature dropped a total of 15 degrees Fahrenheit, the correct number sentence should be:

-15 + (-15) + (-15) + (-15) + (-15) = -75

This number sentence means that the temperature dropped by 15 degrees Fahrenheit each hour for 5 hours, resulting in a total temperature drop of 75 degrees Fahrenheit.
