8x=5y and 3y=14z then 12x= how many z's

**Steve**, Sunday, December 9, 2012 at 8:20pmyou know that 8x = 5y

you know that 3y=14z

since 5 = (5/3)*3, 5y = (5/3)*(3y) so,

5y = (5/3)(3y) = (5/3)(14z) = (70/3)z

now you have 5y, which is the same as 8x. You want 12x.

since 12 = (3/2)*8, 12x = (3/2)*8x.

12x = (3/2)(8x) = (3/2)(5y) = (3/2)(70/3)z = (70/2)z = 35z

Don't know how I can clear it up any more.

so

y = (14/3) z

8 x = 5 (14/3) z

x = (5/8)(14/3)z

12 x = 12(5/8)(14/3)z = 35 z
