Answer:
The consultant sold 15 circular stones and 22 rectangular ones
Step-by-step explanation:
let quantity of circular stones be X , rectangular ones be Y
thus:,We can deduce that,
26x+34y=1138...... equation 1
He sold total of 37 ,both stones
x+y=37... equation 2
Solving simultaneously
make Y subject of the formula in equation 1
34y=1138-26x
Going left to write >,<,>,>,>,>,>,<
Answer:
190

20C2 = (20*19)/(1*2) = 190
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>
