5x=

The temperature decreased by
° every hour.

Answer 1

The temperature dropped by 12° in 5 hours. This means that the temperature dropped the same amount every hour.

To determine the amount of change, x, of temperature every hour, we need to divide the total temperature drop by the number of hours:

x = total temperature drop / number of hours
x = 12° / 5 hours

Simplifying, we have:

x = 2.4°

Therefore, the equation that represents the amount of change, x, of temperature every hour is:

5x = 5 * 2.4° = 12°
