Question

the temperature in Chicago is -9 Fahrenheit when Brenna woke up by her lunch hour the temperature was 5 Fahrenheit what integer represents the change in temperature

Answer 1

Answer:

14 degrees

Step-by-step explanation:

Current Temp minus Previous Temp

5 -  (-9) = ?

Note: Subtracting a negative number converts to addition

5 + 9 = 14

Another way to think of this is that the air must first heat up 9 degrees to reach ZERO, then the air heats up another 5 degrees.   9 + 5 = 14

-or-

On a number line count the whole numbers between the Low and High.

-10  -9  -8  -7  -6  -5  -4  -3  -2  -1    0   1    2    3   4   5    6   7   8  9  10
