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 can be found by adding the change in temperature to the initial temperature.
Therefore, the temperature now is 13°C + (-18.6°C) = -5.6°C.
Use the additive inverse to find −492.89−(−871.78).
To find the expression −492.89 − (−871.78), we can rewrite it as −492.89 + 871.78.
Adding the two numbers gives us 378.89.
Therefore, −492.89 − (−871.78) = 378.89.

To find the distance between -18.26 and -2.45 on a number line, we subtract the two values and take the absolute value of the result.
|-18.26 - (-2.45)| = |-18.26 + 2.45| = |-15.81| = 15.81
Therefore, the distance between -18.26 and -2.45 on a number line is 15.81.
Subtract 24−(−15).
Subtracting 24 - (-15) can be simplified by changing the subtraction of a negative number to addition.
24 - (-15) = 24 + 15
Adding 24 and 15, we get:
24 + 15 = 39
Therefore, the result of the subtraction 24 - (-15) is 39.
