Solve the following problem:

It was 13°C yesterday, but the temperature changed by −18.6° overnight. What is the temperature now?(1 point)
°C

1 answer

To find the current temperature, we need to subtract the change in temperature from the temperature yesterday.

Temperature now = Temperature yesterday - Change in temperature overnight

Temperature now = 13°C - (-18.6°C)

Remember, subtracting a negative is the same as adding a positive.

Temperature now = 13°C + 18.6°C

Temperature now = 31.6°C

Therefore, the temperature now is 31.6°C.
