Question

The forecast predicts that the temperature will change from 15 degrees Fahrenheit to -3 degrees Fahrenheit. A. Write an expression that represents the change in temperatures for Saturday. B. What is the expected temperature change? C. If the temperature actually changes by 5 degrees more than predicted, what will be the change in temperature?

Answer 1

A.
`Change = Final\ temperature - Inicial\ temperature`

B. Negative change of 18 degrees

C. Negative change of 23 degrees, final temperature would be -8°F

Explanation:

A.

The expression that represents the change in temperature is:

`Change = Final\ temperature - Inicial\ temperature`

B.

If the final temperature is -3°F and the inicial temperature is 15°F, the change in temperature is:

`Change = -3 - 15 = -18\° F`

We have an absolute change of 18 degrees.

C.

If the change is 5 degrees more, the change would be 18 + 5 = 23 degrees, and the final temperature would be 5 degrees lower, that is:

`Final\ temperature = -3 - 5 = -8\°F`
