Question

9. The temperature at noon was 84° F and it began to drop 0.8° each hour. If the current temperature is 79.2° F, write and solve an equation to determine the number of hours that have passed.

Answer 1

Answer:6 hours have passed by.

Step-by-step explanation:

0.8x= 84-79.2 where x is the number of hours.

O.8x = 4.8

Divide both sides by 0.8

X= 6
