Half the distance of AC (6)
In order to know how much time will David and
Armando take, you need to write down the given and solve them with the given
solution.
David – 15 reports
Armando – 37 reports
Total Reports = 52 reports in total
Total Reports in an hour = 52
Overall total reports = 400
Time to finish = ?
If you try to evaluate, if you have 50 reports in
an hour with a total of 400 reports, you could have gain 8 hours by doing the
reports.
So to expand more, 52 reports will be divided
into 400, giving a total of 7.6
<span>So the answer is that they will take 7 hours
and a half in doing the reports.</span>

Step-by-step explanation:
Given the expression






Thus,

<u>Answer:</u>
Equivalent expression of (-11x+31y) - 2(-x + 5y) is -9x +21y Hence option C is correct
<u>Solution:</u>
Given expression is (-11x+31y) - 2(-x + 5y)
Need to find equivalent expression from four given option.
Let’s first simplify the given expression
(-11x+31y) - 2(-x + 5y)
On opening the brackets we get
-11x + 31y + 2x -10y
Now bringing similar terms together and performing appropriate operation, we get
-11x + 2x + 31y + -10y
Taking common terms out we get,
=> (-11 + 2) x + (31 -10) y
= -9x +21y
Therefore Equivalent expression of (-11x+31y) - 2(-x + 5y) is -9x +21y.
