At midnight the temperature was -8F. At noon the temperature was 23F. Which expression represents the increase in temperature?
A) -8 - 23
B) {-8} - 23
C) -8 - {23}
D) {-8 - 23}

-[8]-23

what is the increase from 4 to 9? It is 9-4=5, right?

So, the increase from -8 to 23 is 23 - (-8) = 31

thank u

To find the increase in temperature, we need to subtract the initial temperature from the final temperature.

Given that the temperature at midnight was -8F and at noon was 23F, the increase in temperature can be found by subtracting the initial temperature from the final temperature.

So the correct expression would be:

Final temperature - Initial temperature

23 - (-8)

To subtract a negative number, we can change it to addition:

23 + 8

Which simplifies to:

31

Therefore, the correct expression for the increase in temperature is:

31

None of the given options A, B, C or D correctly represent the increase in temperature.
