Question

Challenge in City A, the temperature rises 7°F from 8 A.M. to 9 A. Then the temperature drops

6°F from 9 AM to 10 A.m. In City B, the temperature drops 2°F from 8 A.M. to 9 A.M. Then the
temperature drops 4°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.

Answer 1

City A experiences a 1°F increase, while City B experiences a 6°F decrease in temperature from 8 A.M. to 10 A.M.

Step-by-step explanation:

For City A, the change in temperature from 8 A.M. to 10 A.M. can be represented by the expression 7°F - 6°F. Simplifying this expression, we find that the total change in temperature in City A over the two hours is +1°F (increase by 1°F).

For City B, the temperature change from 8 A.M. to 10 A.M. is represented by the expression -2°F - 4°F. When we simplify this, we get -6°F, which means that the temperature in City B decreased by 6°F.
