Answer: 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

So, change in temperature during the day = 4c - (-7c)

Recall that minis sign multiply by minus sign becomes plus sign ➕

So, 4c - (-7c) = 4c + 7c

= 11c
