Therefore, -492.89 - (-871.78) is equal to -492.89 + 871.78.
Evaluating the sum, we have -492.89 + 871.78 = 378.89.
|-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.
24 - (-15) is equal to 24 + 15.
Evaluating the sum, we have 24 + 15 = 39.
Therefore, the subtraction 24 - (-15) equals 39.
First, let's add the fractions 4/9 and 5/9. The numerators can be added together while keeping the same denominator:
4/9 + 5/9 = (4 + 5)/9 = 9/9 = 1
Next, let's subtract 8 from the result we obtained:
1 - 8 = -7
Finally, let's subtract 10 from the previous result:
-7 - 10 = -17
Therefore, the expression 17 4/9 + 5/9 - 8 - 10 equals -17.
To solve 17 4/9 + 5/9 - 8 - 10, we first add the whole numbers and the fractions separately, and then subtract the remaining numbers:
17 + (4/9) + (5/9) - 8 - 10
Combining the whole numbers, we have:
17 - 8 - 10 = -1
Combining the fractions, we have:
4/9 + 5/9 = (4 + 5)/9 = 9/9 = 1
Now, let's combine the whole number (-1) with the fraction (1):
-1 + 1 = 0
Therefore, the expression 17 4/9 + 5/9 - 8 - 10 equals 0.

Joey walked 15 2/3 meters east and 21 3/4 meters west.
To subtract these distances, we can convert the mixed numbers to improper fractions:
15 2/3 = (3 * 15 + 2)/3 = 47/3
21 3/4 = (4 * 21 + 3)/4 = 87/4
Now, we subtract these fractions:
47/3 - 87/4
To subtract fractions, we need to find a common denominator. In this case, the lowest common denominator is 12:
47/3 = (47/3) * (4/4) = 188/12
87/4 = (87/4) * (3/3) = 261/12
Now we can subtract the fractions:
188/12 - 261/12 = (188 - 261)/12 = -73/12
Therefore, Joey is -73/12 meters away from home.
