Responses

5x+11=−24
5 x plus 11 equals negative 24

−x+3=−4
negative x plus 3 equals negative 4

4x−23=5
4 x minus 23 equals 5

−3x−8=−29

Answer 2

The temperature decreased by 12° in 5 hours, so the temperature decreased by 12/5 = <<12/5=2.4>>2.4° every hour.

Therefore, the equation that represents the amount of change, x, of temperature every hour is 5x = 12.

To solve this equation, we divide both sides by 5:

5x/5 = 12/5

x = 2.4

So, the temperature decreased by 2.4° every hour.
