7. During the month of December, the low temperature was - 23° F and the high temperature was
-2° F. What is the range of December temperature?​

I think around 15°c

Step-by-step explanation:

PLEASE accept me in

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
