brainliest if right pls help

Answer:
C
Step-by-step explanation:
First of all -2-5= -7
It isn't (A) because (A) is saying that the beginning temperature was a postive number, which it wasn't The beginning temperature is -2, which is negative. So we can cross that off.
It isn't (B) because (B) is saying that you start off with -2 and then it gets warmer, and temperature adds up onto it. When you do -2 +5, you get 3, which is not the answer.
So, the answer is c
Proof: It starts of with negative 2, which is the first temperature. Then, it says decreased by 5, which is what is happening. 5 is getting subtracted from -2
So, the answer is C
Answer:
C
Step-by-step explanation:
-2-5
the minus sign infront of the two has to stay with the two so we would have -2°C the options we would be left with are b and c but since it says subtract 5 that would be a decreases not an increase so it would be decrease 5°C
