The outside temperature is -5 degrees and falling at a rate of 3 degrees per hour. What will the outside temperature be in 7 hours

-5 + (-3 * 7) = ?

To find the outside temperature in 7 hours, we need to calculate the change in temperature over that time period.

Given that the current temperature is -5 degrees and it is falling at a rate of 3 degrees per hour, we can determine the change in temperature in 7 hours.

Since the temperature is falling, the change in temperature will be negative. The change in temperature can be calculated by multiplying the rate of change (-3 degrees per hour) by the number of hours (7):

Change in temperature = rate of change * number of hours
Change in temperature = -3 degrees/hour * 7 hours
Change in temperature = -21 degrees

Now, to find the temperature in 7 hours, we need to subtract the change in temperature from the current temperature:

Temperature in 7 hours = Current temperature - Change in temperature
Temperature in 7 hours = -5 degrees - (-21 degrees)
Temperature in 7 hours = -5 degrees + 21 degrees
Temperature in 7 hours = 16 degrees

Therefore, the outside temperature in 7 hours will be 16 degrees.
