On a given morning, the temperature was 71°F. The temperature dropped 5°F and then rose 8°F. How much does the temperature need to rise or fall to return to the initial temperature of 71°F? (1 point)
Fall 8 degrees
Rise 8 degrees
Fall 3 degrees
Rise 5 degrees
The temperature initially dropped 5°F, then rose 8°F.
To return to the initial temperature of 71°F, the temperature needs to rise by the same amount it initially dropped, which is 5°F.
Therefore, the temperature needs to rise 5 degrees.
To return to the initial temperature of 71°F, we need to reverse the changes that occurred.
The temperature initially dropped 5°F and then rose 8°F.
To reverse the drop of 5°F, we need to rise by the same amount, which is 5°F.
Then, to reverse the rise of 8°F, we need to fall by the same amount, which is 8°F.
Therefore, the temperature needs to fall 8 degrees to return to the initial temperature of 71°F.
So the correct answer is: Fall 8 degrees.
To find out how much the temperature needs to rise or fall to return to the initial temperature of 71°F, we need to subtract the total rise in temperature from the total fall in temperature.
The temperature dropped 5°F, so the total fall in temperature is 5°F.
The temperature then rose 8°F, so the total rise in temperature is 8°F.
To calculate how much the temperature needs to rise or fall to return to 71°F, we subtract the total rise from the total fall:
Total fall - Total rise = 5 - 8 = -3°F
Since the result is negative, it means that the temperature needs to fall 3 degrees to return to the initial temperature of 71°F.
Therefore, the correct answer is: Fall 3 degrees.
