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 this equation.
The equation that represents the amount of change, x, of temperature every hour is given by:
x * 5 = -12
To solve for x, we divide both sides of the equation by 5:
x = -12 / 5
Therefore, the temperature drops by -12/5 degrees every hour.
