Answer:
See below.
Explanation:
to find the change in temperature from 2:00 PM to 10:00 PM, you need to subtract the final temperature from the initial temperature. In other words,
Change in temperature = Final temperature - Initial temperature
In your problem, the final temperature is -9°F and the initial temperature is 18°F. Therefore,
Change in temperature = -9°F - 18°F
Change in temperature = -27°F
So, the change in temperature from 2:00 PM to 10:00 PM is -27°F.
