Question

Challenge in City A, the temperature rises 6°F from 8 Am. to 9 Am. Then the temperature drops 5°F

from 9 A.m. to 10 a.m. In City B, the temperature drops 1°F from 8 A.m. to 9 Am. Then the temperature
drops 3°F from 9 a.m. to 10 A.m. Write an expression that represents the change in temperature from 8
A.M. to 10 A.m. for each city. Simplify and interpret each sum.

Which expression represents the change in temperature for City A?

A) -6 + (-5).
B) -6 + 5.
C) 6 + 5.
D) 6 + (-5.

Answer 1

The expression that represents the change in temperature for City A is 6 + (-5).

Step-by-step explanation:

The expression that represents the change in temperature for City A is D) 6 + (-5).

To find the change in temperature, we add the increase and decrease in temperature. The temperature rises 6°F from 8 am to 9 am, which is represented as +6. Then, the temperature drops 5°F from 9 am to 10 am, which is represented as -5. Adding the two values gives us 6 + (-5), which simplifies to 1. Therefore, the change in temperature for City A is 1°F.
