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.
