On a given morning, the temperature was 64 degrees. The temperature dropped 7 degrees and then rose 11 degrees. How much does the temperature need to rise or fall to return to the initial temperature of 64 degrees?
fall 4 degrees
rise 3 degrees
fall 7 degrees
rise 11 degrees
To return to the initial temperature of 64 degrees, the temperature needs to fall by 7 degrees and rise by 11 degrees. Therefore, the temperature needs to fall by 7 degrees and rise by 11 degrees, totaling a change of 18 degrees.
To answer this question, we need to consider the initial temperature of 64 degrees and the changes in temperature that occurred afterwards.
The temperature dropped 7 degrees, so we subtract 7 from 64: 64 - 7 = 57 degrees.
Then, the temperature rose 11 degrees, so we add 11 to 57: 57 + 11 = 68 degrees.
Finally, we need to figure out how much the temperature needs to rise or fall to return to the initial temperature of 64 degrees. We subtract 64 from 68: 68 - 64 = 4 degrees.
Therefore, the temperature needs to fall 4 degrees to return to the initial temperature of 64 degrees.
