Question

On a given morning the temperature was 81 degree farinheight . The Temperature dropped 9 degree farinheight and then rose 5 degree farinheight. How mush does the temperature need to rise or fall to return to the initial temperature of 81 degree farinheight

Answer 1

The temperature initially dropped by 9 degrees Fahrenheit and then rose by 5 degrees Fahrenheit.

To return to the initial temperature of 81 degrees Fahrenheit, we need to undo the changes made:

81 degrees Fahrenheit + 9 degrees Fahrenheit - 5 degrees Fahrenheit = 85 degrees Fahrenheit.

Therefore, the temperature needs to rise by 4 degrees Fahrenheit to return to the initial temperature of 81 degrees Fahrenheit.
