To find the additive inverse of a number, we simply change its sign.

The additive inverse of -2445 is 2445.
The additive inverse of -6710 is 6710.

Thus, -2445 - 6710 can be rewritten as 2445 + 6710.

Adding these two numbers gives us 9155.

Therefore, the correct answer is 9155.

To determine the distance between two numbers on a number line, we subtract the smaller number from the larger number and take the absolute value of the result.

In this case, 6.5 is the larger number and -7.2 is the smaller number.

6.5 - (-7.2) = 6.5 + 7.2 = 13.7

Taking the absolute value of 13.7 gives us the distance between the two numbers.

Therefore, the correct answer is 13.7.

Subtracting -8 from -6 means adding the opposite of -8. The opposite of -8 is 8, so the expression becomes -6 + 8.

-6 + 8 = 2

Therefore, the correct answer is 2.
