Hi there! The answer is A. - 22
We can use PEMDAS to find our answer, which says divide first (before adding).
- 24 - 8 : (-4) =
Since we divide two negative numbers, we end up with a positive value.
- 24 + 2 =
Now we can add
-24 + 2 = -22
The two bars ( | | ) symbolize absolute value
Absolute value is essentially just making the number given positive.
If the given number is already positive then the absolute value is the same as the original number
|-13| is 13
The absolute value of -13 is 13
Hope this helped!

Our inequality looks like this:
2(x+6)≤52
Using the Distributive Property, we have
2*x + 2*6 ≤52
2x+12≤52
Cancel the 12 by subtracting from both sides:
2x+12-12≤52-12
2x≤40
Divide both sides by 2:
2x/2 ≤ 40/2
x≤20
x cannot be any more than 20 to satisfy this inequality.
