It was 13°C yesterday, but the temperature changed by −18.6° overnight. What is the temperature now?(1 point)
$$°C
The temperature now can be calculated by subtracting 18.6 from 13:
13°C - 18.6°C = -5.6°C
So the temperature now is -5.6°C.
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 from yesterday's temperature:
Current temperature = Yesterday's temperature + Change in temperature
Current temperature = 13°C + (-18.6°C)
Current temperature = 13°C - 18.6°C
Current temperature = -5.6°C
Therefore, the temperature now is -5.6°C.
To find the current temperature after the overnight change, we need to subtract the change in temperature from the temperature yesterday. So, we will subtract −18.6° from 13°C.
To subtract a negative number, we can simply add its positive value. In this case, since −18.6° is negative, we'll add its positive value, which is 18.6°.
Therefore, to find the temperature now, we perform the following calculation:
13°C + 18.6° = 31.6°C
So, the temperature now is 31.6°C.
