Answer:

 72.3 + (-39.1)

Step-by-step explanation:

Temperature before the ice cubes

72.3

Temperature after the ice cubes

T

Decrease was 39.1

Final temperature = beginning temperature - decrease

                        72.3 - 39.1

Rewriting as a sum

                       72.3 + (-39.1)

Answer:

72.3 °F + (-39.1 °F)

Step-by-step explanation:

Add the original temperature and the change in temperature to find the new temperature.

The original temperature is 72.3 °F.

The change in temperature is -39.1 °F.

Now we add the temperatures:

72.3 °F + (-39.1 °F)

Answer: 72.3 °F + (-39.1 °F)
