Question

so i just started modeling and two step inequalities and my question is 62°f and it drops 2 degrees every hour .How many hours was it before the temperature was below 40°

Answer 1

Answer:

11 hours

Equation:

62 - 2x = T

62 - 2(11) = 40

Answer 2

It was 11 hours because if the temperature drops 2 degrees after every hour, after 11 hours, the temperature would have dropped 22 degrees and 62 - 22 = 40.
