Question 18346: A set of children's blocks contains 3 shapes: Longs, flats & cubes
There are 3 times as many longs as cubes and 30 fewer flats than longs. If there are 600 blocks in all, how many longs are there? Answer by pwac(253) (Show Source):
You can put this solution on YOUR website! let x=cubes
so 3x is amount of longs
and flats=3x-30
put these together to total 600
x+3x+3x-30=600
7x-30=600 add 30 to both sides
7x=630 divide both sides by 7
x=90
so number of longs =3x = 3 X 90=270
270 longs
