To find -492.89 - (-871.78) using the additive inverse, you can rewrite the expression as -492.89 + 871.78.

Adding the two numbers together:

-492.89 + 871.78 = 378.89

To determine the distance between -18.26 and -2.45 on a number line, we can subtract the two numbers and take the absolute value of the result.

|-18.26 - (-2.45)| = |-18.26 + 2.45| = |-15.81| = 15.81

Therefore, the distance between -18.26 and -2.45 on a number line is 15.81.

To solve the expression 2 - |1/3 * -9| - 5, we can first simplify the absolute value term and then evaluate the expression.

First, let's look at the absolute value term |1/3 * -9|:

|1/3 * -9| = |-3| = 3

Now we can substitute this value back into the original expression:

2 - |1/3 * -9| - 5 = 2 - 3 - 5 = -6

Therefore, the solution to the expression 2 - |1/3 * -9| - 5 is -6.

To solve the expression 24 - (-15), we can simplify the subtraction involving the negative number:

24 - (-15) = 24 + 15

Now, we can add the two numbers together:

24 + 15 = 39

Therefore, the solution to the expression 24 - (-15) is 39.

To solve the expression 17 4/9 + 5/9 - 8 - 10, we first need to convert the mixed number into an improper fraction:

17 4/9 can be written as (9 * 17 + 4)/9 = 157/9

Now, we can substitute these values back into the original expression:

17 4/9 + 5/9 - 8 - 10 = 157/9 + 5/9 - 8 - 10

Next, we can combine like terms by adding/subtracting the fractions and the whole numbers:

(157/9 + 5/9) - 8 - 10 = (162/9) - 8 - 10

Now, we can simplify the fraction by dividing the numerator by the denominator:

162/9 = 18

Replacing this in our expression:

18 - 8 - 10 = 18 - 18

Finally, we subtract to find the result:

18 - 18 = 0

Therefore, the solution to the expression 17 4/9 + 5/9 - 8 - 10 is 0.

To find the change in temperature during the three hours from 9 a.m. to noon, we can subtract the temperature at 9 a.m. from the temperature at noon.

The equation to represent the change in temperature is:

Change in Temperature = Temperature at Noon - Temperature at 9 a.m.

Change in Temperature = (-1.6) - (-5.8)

Change in Temperature = -1.6 + 5.8

Change in Temperature = 4.2

The change in temperature during these three hours is 4.2 degrees Celsius.

This means that the temperature increased by 4.2 degrees Celsius from 9 a.m. to noon.
