at 2:00 pm the temperature is 18°f. at 10:00 pm the temperature is -9°f. what is the change in temperature…

Explanation:

Step1: Identify initial and final temps

Initial temp = $18^{\circ}F$, Final temp = $- 9^{\circ}F$

Step2: Calculate temp change

Change = Final - Initial = $-9 - 18$ $=-9+( - 18)=-27^{\circ}F$. We take the absolute - value for the magnitude of change. So the change is $27^{\circ}F$.

Answer:

$27$
