Solve the following problem:
It was 13° C yesterday, but the temperature changed by −18.6° overnight. What is the temperature now?(1 point
The temperature now is the sum of the temperature yesterday and the change overnight.
Temperature now = Temperature yesterday + Change overnight
Temperature now = 13° C + (-18.6° C)
To find the sum of two numbers with different signs, we can subtract their absolute values and assign the sign of the number with the larger absolute value.
Absolute value of 13° C = 13° C
Absolute value of -18.6° C = 18.6° C
18.6° C is larger than 13° C, so the temperature change is negative.
Temperature now = 13° C - 18.6° C
Temperature now = -5.6° C
Therefore, the temperature now is -5.6° C.
To find the current temperature, you need to subtract the change in temperature from the initial temperature.
1. Start with the initial temperature: 13° C
2. Subtract the change in temperature: 13° C - (-18.6°) = 13° C + 18.6° = 31.6° C
Therefore, the current temperature is 31.6° C.
To find the temperature now, we need to determine the change in temperature overnight and subtract it from the initial temperature.
The problem statement tells us that the temperature changed by −18.6° overnight. To account for this change, we subtract 18.6° from the initial temperature of 13°.
13° C - 18.6° = -5.6° C
Therefore, the temperature now is -5.6° C.
