To find the sum of -2445 and -6710 using the additive inverse, we need to change the signs of both numbers and then add them together.
The additive inverse of -2445 is 2445, and the additive inverse of -6710 is 6710.
Therefore, -2445 + -6710 = -2445 + 2445 + (-6710) = 0 + (-6710) = -6710.
So the answer is -6710.

To find the sum of -2445 and -6710 using the additive inverse, we need to change the signs of both numbers and then add them together.
The additive inverse of -2445 is 2445, and the additive inverse of -6710 is 6710.
Therefore, -2445 + -6710 = 2445 + 6710 = 9155.
So the answer is 9155.

To find the sum of -24 4/5 and -6 7/10 using the additive inverse, we need to change the signs of both numbers and then add them together.
The additive inverse of -24 4/5 is 24 4/5, and the additive inverse of -6 7/10 is 6 7/10.
Therefore, -24 4/5 + -6 7/10 = 24 4/5 + 6 7/10 = 30 11/10.
So the answer is 30 11/10.

To determine the distance between 6.5 and -7.2 on a number line, we subtract the smaller number from the larger number.
In this case, the larger number is 6.5 and the smaller number is -7.2.
Therefore, the distance between 6.5 and -7.2 is 6.5 - (-7.2) = 6.5 + 7.2 = 13.7.
So the answer is 13.7.

To solve the mathematical problem involving absolute value, we follow the order of operations (also known as PEMDAS).
First, we evaluate the absolute value expression |2-3|, which equals |-1| = 1.
Next, we perform the division: 21 ÷ 3 = 7.
Then, we add: 7 + 4 = 11.
Finally, we add the absolute value result to the previous sum: 11 + 1 = 12.
So the answer is 12.
