Every 3 weeks 8 students will lose their metro how many will lose it in 9 weeks

First we must divide 9 by 3.

9/3 = 3

Then multiply it by 8

3*8 = 24. Hope this helps!

If eight students lose their metro cards every three weeks then in six weeks sixteen will have lost theirs, and in nine weeks twenty-four will have lost theirs. (I think I did that right)
Hope this helps!

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

The correct answer is c
