Lets use the formula 
to solve this, where,
- R is the rate
- W is the number of workers/things
- T is time
- J is number of jobs/things
<em><u>"If it takes 10 seconds for 10 printers to print out 10 pages of paper"</u></em> - here -
W is 10 printers, T is 10 seconds, and J is 10 pages. We can write:
<u><em>"how many seconds will it take 50 printers to print out 50 pages of paper"</em></u><em> - here we use 
(previously found) to figure out T.</em>
<em>
</em>
So it will take 10 seconds for 50 printers to print 50 pages.

Step-by-step explanation:
2,605 rounded to the nearest hundred......now find the number in the hundreds place...it is the 6....now look at the number to the right of it...if that number is 5 or above, u round the 6 to a 7....but if that number is 4 or below, that 6 stays the same. The number to the right of 6 is 0.....so the 6 stays the same...and ur answer is 2,600.
X+y=15
2x+3y=37
15-x=y
2x+3(15-x)=37
2x+(45-3x)=37
2x-3x+45=37
-1x=-8
x=8
x is the amount of bikes, so there are 8 bikes. 8x2=16.
37-16=21
21/3=7
There are 7 tricycles.
