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

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.

To return to the initial temperature of 81 degrees Fahrenheit, we need to find the difference between the current temperature and the initial temperature.

Given that the temperature dropped 9 degrees Fahrenheit and then rose 5 degrees Fahrenheit, the net change in temperature is -9 + 5 = -4 degrees Fahrenheit.

Since the net change is -4 degrees Fahrenheit, the temperature needs to rise 4 degrees Fahrenheit to return to the initial temperature of 81 degrees Fahrenheit.

To answer this question, we need to determine the temperature change after it dropped 9 degrees Fahrenheit and then rose 5 degrees Fahrenheit.

First, let's calculate the new temperature after the drop of 9 degrees Fahrenheit. We subtract this value from the initial temperature of 81 degrees Fahrenheit:

81 - 9 = 72 degrees Fahrenheit

Next, we need to calculate the temperature after it rose 5 degrees Fahrenheit. We add this value to the temperature after the drop:

72 + 5 = 77 degrees Fahrenheit

Now, to find out how much the temperature needs to rise or fall to return to the initial temperature of 81 degrees Fahrenheit, we subtract the current temperature from the initial temperature:

81 - 77 = 4 degrees Fahrenheit

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