The temperature dropped by 12° in 5 hours. The temperature dropped the same amount every hour. Complete the equation that represents the amount of change,x, of temperature every hour and solve the equation. 5x= the temperature decreased by ° every hour.
The equation that represents the amount of change, x, of temperature every hour is 5x = -12.
To solve the equation, divide both sides by 5:
x = -12/5
Therefore, the temperature decreased by -12/5 or -2.4 degrees every hour.
