11c
Step-by-step explanation:
At 5am the temperature was = -7c.
In the afternoon (12 noon to 4pm) the temperature = 4c .
The change in temperature during the day = Final temperature - Initial temperature

Recall that minis sign multiply by minus sign becomes plus sign ➕
So, 4c - (-7c) = 4c + 7c
= 11c
