The temperature at 10 A.M. was -4degreeF. By noon the temperature had risen by 8degreeF. At 8 P.M., the temperature had dropped 10degree F. What was the temperature at 8 P.M.?

-4 + 8 - 10 = ?

To find the temperature at 8 P.M., we need to start with the temperature at noon and then consider the drop in temperature at 8 P.M.

Given:
Temperature at 10 A.M. = -4°F
Rise in temperature by noon = 8°F
Drop in temperature at 8 P.M. = 10°F

Step 1: Add the rise in temperature to the temperature at 10 A.M.
-4°F + 8°F = 4°F

Step 2: Subtract the drop in temperature at 8 P.M. from the temperature at noon.
4°F - 10°F = -6°F

Therefore, the temperature at 8 P.M. was -6°F.

To find the temperature at 8 P.M., we need to start with the temperature at noon and consider the changes in temperature throughout the day.

Given that the temperature at 10 A.M. was -4°F and had risen by 8°F by noon, we can calculate the temperature at noon by adding the increase in temperature to the initial temperature:
-4°F + 8°F = 4°F

So, the temperature at noon was 4°F.

Next, we need to account for the drop in temperature from noon to 8 P.M. The temperature dropped by 10°F, so we subtract this decrease from the temperature at noon:
4°F - 10°F = -6°F

Therefore, the temperature at 8 P.M. was -6°F.
