Help Me Please!The temperature has been going down at a constant rate. In 4 hours it went down 12 degrees. Which expression best shows the temperature change each hour?A.−12 × -4B.12×4C.−12÷4D.12÷4(Sorry I already did myself! But you can still answer!)

Answer:−12 ÷ 4 expression best shows the temperature change each hour. Hence Option C is correctSolution:Given that, the temperature has been going down at a constant rate. In 4 hours it went down by 12 degrees. Now, we have to choose the correct option which best describes about the change in temperature for each hour. Now, we know that, 12 degrees decreased in 4 hours. Then, number of degrees decreased in one hour = [tex]\frac{\text {total change in temperature.}}{\text {number of hours}}[/tex]Number of degrees changed in one hour = [tex]\frac{12}{4}[/tex]Because the temperature is decreasing we have to add a (-) symbol before the change in degrees. So, now, number of degrees changed in 1 hour = [tex]\frac{-12}{4}[/tex]Hence, the correct option is option c.
