The temperature is 45°F. The temperature will decrease by 2°F each hour. Let h be the number of hours.
Varvara68 [4.7K]
45 - 2t < 32 ( where t is time and you can replace it with x or h if you prefer)
Solving for t you get:
45 - 2t - 32 < 0
45 - 32 < 2t
13 < 2t
13/2 < t
Or the temperature will drop below 32F after 6 and a half hours
