The temperature has been going down at a constant rate. In 8 hours it went down 16 degrees. Which expression best shows the temperature change each hour?

None.

90 i got it

To find the temperature change each hour, we need to calculate the difference in temperature between the starting and ending points and divide it by the number of hours.

In this case, the temperature went down 16 degrees in 8 hours. To find the temperature change each hour, we divide the total temperature change (16 degrees) by the number of hours (8).

The expression would be:

16 degrees / 8 hours

Simplifying this, we get:

2 degrees/hour

Therefore, the expression that best shows the temperature change each hour is 2 degrees/hour.
