Use the additive inverse to find −492.89−(−871.78).
To find the sum -492.89 - (-871.78), we can rewrite it as -492.89 + 871.78. Using the additive inverse, we change the subtraction operation to addition and change the sign of the second number.
Therefore, -492.89 - (-871.78) is equal to -492.89 + 871.78.
Evaluating the sum, we have -492.89 + 871.78 = 378.89.
Determine the distance between −18.26 and −2.45 on a number line.
To find the distance between -18.26 and -2.45 on a number line, we take the absolute value of their difference.

|-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.
Subtract 24−(−15).
To subtract 24 - (-15), we can use the additive inverse to change the subtraction into addition and change the sign of the second number.

24 - (-15) is equal to 24 + 15.

Evaluating the sum, we have 24 + 15 = 39.

Therefore, the subtraction 24 - (-15) equals 39.
What is 17 4/9 + 5/9 − 8 − 10?
To solve the expression 17 4/9 + 5/9 - 8 - 10, we need to add and subtract the numbers in the proper order.

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.
Wrong
Apologies for the incorrect response. Let's solve the expression correctly.

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.
Can you write AI proof essays
Yes, I can help generate an essay or provide assistance in writing an essay. However, it's important to note that as an AI, I can't fully understand the context, purpose, and requirements of the essay in the same way a human writer would. Therefore, it's essential for you to provide specific instructions, topic, and any necessary guidelines or criteria to ensure the essay meets your needs.

Joey walked east for 15 2/3 meters from home. Then, he walked west for 21 3/4 meters. How far was Joey from home? Write your answer as a mixed number only.
To determine how far Joey is from home, we need to find the difference between the distance he walked east and the distance he walked west.

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.
