Step-by-step explanation:
Absent= 6
Total student = 40

For this case we must simplify the following expression:

So, solving the first parentheses we have:

We have to:

We add similar terms taking into account that different signs are subtracted and the sign of the major is placed:

Finally, the simplified expression is: 
ANswer:

<span>Simplify 8 - {x - (5 + x)}:
Order of operations rules require that you perform work inside parentheses first. Thus, do this first: </span>x - (5 + x) => x - 5 - x => -5.
Now we have the following: 8 - {-5} => 8+5 = 13 (answer)
Please note: To avoid confusion, please separate answer choices, such as <span>3 13 -2x + 3 -2x + 13, by using commas or by putting each choice on its own new line:
</span><span>3
13
-2x + 13
I was and still am unsure of what you meant here.</span>
x km : 7,735 m
kilometers : meters = 1 : 1,000
(1 meter) ÷ (1,000)
1 meter = 0.001 km
7,735 meters = 7.735
Correct Answer = A) 7.735 km
