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?
To return to the initial temperature of 71°F, the temperature needs to rise 5°F.
Simplify |-5| + |6|.
To find out how much the temperature needs to rise or fall to return to the initial temperature of 71°F, we'll calculate the net change in temperature.
Given:
Initial temperature = 71°F
Temperature dropped by 5°F
Temperature rose by 8°F
To calculate the net change in temperature, we'll add the individual changes together:
Net Change = (Temperature Drop) + (Temperature Rise)
Net Change = -5°F + 8°F
Net Change = 3°F
Therefore, the temperature needs to rise by 3°F to return to the initial temperature of 71°F.
To calculate how much the temperature needs to rise or fall to return to the initial temperature of 71°F, you need to find the net change in temperature.
First, the temperature dropped 5°F. So, you need to subtract 5 from the initial temperature:
71°F - 5°F = 66°F
Next, the temperature rose 8°F. So, you need to add 8 to the current temperature:
66°F + 8°F = 74°F
Now we can compare the final temperature to the initial temperature to find the net change:
Final temperature - Initial temperature = Net change in temperature
74°F - 71°F = 3°F
Therefore, the temperature needs to rise or fall by 3°F to return to the initial temperature of 71°F.
