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.
5x= __
The temperature decreased by __° every hour.
The equation for the amount of change, x, of temperature every hour would be:
x = (change in temperature) / (number of hours)
Since the temperature dropped by 12° in 5 hours, the change in temperature would be -12° (negative because it's a drop) and the number of hours would be 5.
Therefore, the equation becomes:
x = -12° / 5 = -2.4°
So, 5x = 5 * (-2.4°) = -12°
The temperature decreased by 2.4° every hour.
