The Temperature is 50F. The temperature will decrease by 4F each hour. Let h be the numbers of hours. When will the temperature below 32F

Write inequality for this equation.

C. and D. arrows are suppose to have lines under them.

A. 50 - 4h< 32

B. 50 + 4h < 32

C. 50 + 4h <_32

D. 50 - 4h <_ 32

a. 50 - 4h < 32

Step-by-step explanation:

The question is "When will the temperature be below 32F?" so it can't be less than or equal to (≤), it has to be less than (<).

If the temperature is decreasing every hour you have to decrease 4 for each hour.

hope that helps!

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86
