if x, y, and z are positive numbers and 2x=3y=4z, then the value of x+y+z is how many times the value of x? and why?
\[x=z\] \[z=\frac{1x}{2}\] \[y=\frac{2x}{3}\]
\[x+y+z=x+\frac{ 1x }{ 2 }+\frac{ 2x }{ 3 }\]
thank you so much =)
Don't forget to add the fractions.
Here is a link to help you get around in openstudy (just in case) Don't forget to medal the guy who made tutorial. http://openstudy.com/study#/updates/543de42fe4b0b3c6e146b5e8
Do you need help getting the final answer?
is it 13/6?
Don't forget x. :) \[\frac{13x}{6}\]
thank you so much =)
Another way to get the same answer W = x+y+z W = 12(x+y+z)/12 W = (12x+12y+12z)/12 W = (6*2x+4*3y+3*4z)/12 W = (6*2x+4*2x+3*2x)/12 W = (12x+8x+6x)/12 W = (26x)/12 W = (13/6)*x
that is really helpful as well thank you =)
Where did you get the 12 from?
