Solve the following problem:
It was 13°C yesterday, but the temperature changed by −18.6° overnight. What is the temperature now?(1 point)
To solve the problem, we need to subtract the change in temperature (-18.6°C) from the original temperature (13°C).
13°C - 18.6°C = -5.6°C
Therefore, the temperature now is -5.6°C.
Use the additive inverse to find −492.89−(−871.78).(1 point)
To find -492.89 - (-871.78), we can rewrite the second term as the additive inverse of -871.78, which is 871.78:
-492.89 - (-871.78) = -492.89 + 871.78
Now we can add the two numbers:
-492.89 + 871.78 = 378.89
Therefore, -492.89 - (-871.78) = 378.89.

To determine the distance between -18.26 and -2.45 on a number line, we subtract the smaller value from the larger value:
|-18.26 - (-2.45)| = |-18.26 + 2.45|
|-18.26 + 2.45| = |-15.81|
The absolute value of -15.81 is 15.81.
Therefore, the distance between -18.26 and -2.45 on a number line is 15.81.
