Answer 2

Answer:

21°C

Step-by-step explanation:

If the temperature was -5° in the morning and 16° in the morning, then that means there was an increase in temperature. To find the exact change in temperature, we need to find what plus -5 would be equal to 16.

-5 + x = 16

-5+5 + x = 16+5

x = 21

From this, we can see that the change in temperature was 21°C.
