Solve the mathematical problem involving absolute value.
2−|1/3⋅−9|−5(1 point)
2 - |1/3 * -9| - 5
First, perform the multiplication inside the absolute value:
2 - |(-9/3)| - 5
Simplify the division within the absolute value:
2 - |(-3)| - 5
Since the absolute value of a negative number is its positive counterpart, we get:
2 - 3 - 5
Combine like terms:
-1 - 5 = -6
Therefore, 2 - |1/3 * -9| - 5 equals -6.
Subtract 24−(−15).
To subtract 24 - (-15), we can rewrite the expression as 24 + 15:
24 + 15 = 39

To solve 17 4/9 + 59 - 8 - 10, first convert the mixed number to an improper fraction and then add and subtract:
17 4/9 = (17 * 9 + 4) / 9 = 157/9
Now, let's simplify the expression:
157/9 + 59 - 8 - 10
To add and subtract fractions and whole numbers, we need to find a common denominator. In this case, the common denominator is 9:
157/9 + 59 * 9/9 - 8 * 9/9 - 10 * 9/9
157/9 + 531/9 - 72/9 - 90/9
Now, combine the fractions:
(157 + 531 - 72 - 90) / 9
526 / 9
Now, let's divide 526 by 9:
526 ÷ 9 = 58 remainder 4
So, the answer is 58 4/9, or in mixed number form, 58 and 4/9.

17 4/9 = (17 * 9 + 4) / 9 = 157/9
Now, let's simplify the expression:
157/9 + 5/9 - 8 - 10
To add and subtract fractions and whole numbers, we need to keep a common denominator. In this case, the common denominator is 9:
(157 + 5) / 9 - 8 - 10
162/9 - 8 - 10
Now, combine the fractions:
(162 - 72 - 90) / 9
Now, subtract 72 and 90 from 162:
162 - 72 - 90 = 0
So, the final expression is 0/9, which simplifies to 0. Therefore, the answer is 0.
