Question

On Tuesday, Emma’s thermometer showed a temperature of -8 degrees when she woke up. The temperature then rose 1 degree every hour. Write an expression that represents the temperature change on Tuesday. Use the variables t for temperature and h for hours.

A. t+h
B. t-h
C. t+1h
D. t-1h

Answer 1

The expression that represents the temperature change on Tuesday is t+1h.

Step-by-step explanation:

The expression that represents the temperature change on Tuesday is t+1h.

The variable t represents the initial temperature of -8 degrees, and the variable h represents the number of hours. Since the temperature rises by 1 degree every hour, we add 1 to the initial temperature for each hour. Therefore, the expression is t+1h.
