Question

The temperature in the afternoon was 10 degrees. By 8 pm, the temperature was -5

Answer 1

Answer:

The temperature had dropped by 15 degrees (-15 if you don't want it positive.)

Step-by-step explanation:

Okay!

This is a subtraction problem.

If it started off at 10, and went down to -5, we can do |-5 - 10| (I am using the two bars because it said change.) And we get 15!

Answer 2

10-10 and then -5
So 10+ 5= 15
So the temperature would chance -15 degrees
