the temperature changed from 5°F at 6:00pm to -2°F at midnight. how much did the temperature decrease

well, it went down 5° to 0°

then it went down another 2° to -2°
right?

Plot these two numbers on the number line and see how far apart they are.

To find the decrease in temperature, we subtract the final temperature from the initial temperature.

The initial temperature was 5°F.

The final temperature was -2°F.

To calculate the decrease, we subtract the final temperature from the initial temperature:

5°F - (-2°F) = 5°F + 2°F = 7°F.

Therefore, the temperature decreased by 7°F.

To determine how much the temperature decreased, we need to subtract the final temperature from the initial temperature.

The initial temperature was 5°F at 6:00pm, and the final temperature was -2°F at midnight.

To find the decrease in temperature, subtract the final temperature (-2°F) from the initial temperature (5°F):

5°F - (-2°F) = 5°F + 2°F = 7°F

Therefore, the temperature decreased by 7 degrees Fahrenheit.
