Since 7 pages could be in 5 min.
So time required by 1 page 5/7 min.
So time required by 175 pages =175×5/7=125 min.
= 2 hours and 5minutes
2880 books
Divide 1920 by 40
Then multiply the number by 2
You will get 96
Then multiply it by 30
It will be a J-shaped graph. As X increases, Y will increase at a sharper rate, so it will look exactly like a J when graphed
X - 6y=18
2x-3y=9 |*-2
x -6y=18
-4x+6y=-18
----------------
-3x=0, x=0
2x-3y=9
2*0-3y=9
-3y=9, y=-9/3, y= -3
