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

The temperature now is -5.6°C.

why?

pls explain

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

Yesterday's temperature: 13°C
Change in temperature: -18.6°C

To find the current temperature, we subtract the change in temperature from yesterday's temperature.

Current temperature = Yesterday's temperature + Change in temperature
= 13°C + (-18.6°C)
= -5.6°C

Therefore, the current temperature is -5.6°C.
