Question

In Coachella, California the temperature was 9 degrees below zero at 2 am. By 5 am the temperature had dropped by an additional 7 degrees. By 1 pm the next day the temperature had risen by 12 degrees. What was the temperature at 5 am

Answer 1

Answer:

The temperature at 5 am is 16 degrees below zero.

Step-by-step explanation:

The temperature at 2 am is 9 degrees below zero:

$T_{2_{am}} = -9$

Since at 5 am the temperature had dropped by an additional 7 degrees, we have:        

$T_{5_{am}} = T_{2_{am}} - 7$      

$T_{5_{am}} = -9 - 7 = -16$

Therefore, the temperature at 5 am is 16 degrees below zero.

I hope it helps you!
