The temperature is 45°f. the temperature will decrease by 2°f each hour. let h be the number of hours. when will the temperature be below 32°f? write an inequality for this problem.

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

It equals 1373.5 that’s the solution

Basic algebra equation. first set up your equation: divide out 9.and now you are left with 2x + 4 = 8.
