it's \( \frac{m+t}{m-t} \) isn't ?
OpenStudy (aroub):
yes
OpenStudy (anonymous):
m =2.5t
m+t/m-t
= 3.5t / 0.5t
= 7
OpenStudy (anonymous):
\( 20m = 50t \Rightarrow m = \frac 52 t \) now substitute in \( \frac{m+t}{m-t} \)... can you do the rest ?
OpenStudy (aroub):
Oh and btw the answer is 7/3 ( i just don't know how to get there :(
@Fool , I just substitute the m and solve?

You have to substitute twice in order to get 7/3
hero (hero):
Or just put everything in terms of one variable
