I think that’s 4 degrees, I might have to check my answer.

Answer:

-4 + 8 = 4

Step-by-step explanation:

If the temperature starts at -4 and gets warmer you are going to add because the numbers are increasing. Start at -4 because that time (7 AM) comes first. Next, add 8 because it got warmer. If you add a positive and a negative you are actually going to subtract. 8-4=4. Take the sign of the bigger number. For example, 8 is bigger than 4 and 8 is positive so the answer will be positive.
