It was 13° C yesterday, but the temperature changed by −18.6° overnight. What is the temperature now?(1 point)
The temperature now would be 13°C + (-18.6°C) = -5.6°C.
Use the additive inverse to find −492.89−(−871.78) .
To find −492.89 − (−871.78), we can rewrite this expression as −492.89 + (871.78) using the additive inverse.
So, −492.89 − (−871.78) = −492.89 + 871.78
Now we can add the numbers:
−492.89 + 871.78 = 378.89
Therefore, −492.89 − (−871.78) = 378.89
Determine the distance between −18.26 and −2.45 on a number line.(1 point)
To determine the distance between −18.26 and −2.45 on a number line, we subtract the two numbers and take the absolute value of the result.
|−18.26 - (-2.45)| = |−18.26 + 2.45|
Simplifying the calculation inside the absolute value:
|−18.26 + 2.45| = |-15.81| = 15.81
Therefore, the distance between −18.26 and −2.45 on a number line is 15.81 units.
Subtract 24−(−15) .
To subtract 24 - (−15), we can rewrite this as 24 + 15 using the additive inverse.
So, 24 - (−15) = 24 + 15 = 39.
Therefore, 24−(−15) is equal to 39.
