Question:

In 1924, the temperature in Fairfield, Montana, dropped from 63 degrees to -21 degrees in 12 hours. What was the change in temperature? PLS ANSWER ASAP

Answers

-42

Step-by-step explanation:

because if you do 63 - -42 it equals -21

Step-by-step explanation:63 +21=84

Average hourly change = (63 - (-21))/12 = (63 + 21)/12 = 84/12 = 7 degrees Fareinheit

If you add 63 and 21 you get 84. Next you would do 84 divided by 12 which would equal 7

The average change hourly is 7 degrees per hour

The answer would be -42.
