How many equal sides does an icosahedron have?

Twenty

A farmer grows 252 kilograms of apples. He sells them to a grocer who divides them into 5 kilogram and 2 kilogram bags. If the grocer uses the same number of 5 kg bags as 2kg bags, then how many bags did he use in all?

72 bags

x=total number of bags

5(1/2 x) + 2 (1/2 x) = 252

2.5x + 1x = 252

3.5x = 252

x = 72 bags.

Are these correct?

**Steve**, Thursday, March 29, 2012 at 11:41amYou got an answer for x, but he used 1/2 x of each kind of bag.

so, 36 of each bag.

36(5+2) = 252
