Bot use the additive inverse to find -492.89 - (-871.78).

Answer 1

To use the additive inverse to find the expression -492.89 - (-871.78), we can rewrite the expression as follows:

-492.89 + 871.78

Now we can add the positive value of -492.89 to 871.78:

871.78 - 492.89 = 378.89

Therefore, -492.89 - (-871.78) is equal to 378.89.

Answer 2

Bot determine the distance between -18.26 and -2.45 on a number line. Pick one of these answers. -20.71 20.71 -15.81
15.81

Answer 3

To determine the distance between -18.26 and -2.45 on a number line, we need to subtract the smaller number from the larger one and take the absolute value of the result.

|-2.45 - (-18.26)| = |-2.45 + 18.26|

Now we can add the positive value of -2.45 to 18.26:

18.26 + 2.45 = 20.71

Therefore, the distance between -18.26 and -2.45 on a number line is 20.71.
