Hmm, I'm not very sure, as I'm not so good at geometry, and I don't want to mislead you, sorry.

OpenStudy (anonymous):

okay thanks could you try another problem? is there anyone else who could help me?

OpenStudy (astrophysics):

@phi is good at these kinds of problems

OpenStudy (anonymous):

ok thanks

OpenStudy (astrophysics):

Np, good luck!

OpenStudy (anonymous):

thanks!

OpenStudy (misty1212):

HI!!

OpenStudy (misty1212):

you could try \[\frac{2x}{15}=\frac{x+2}{12.5}\]

OpenStudy (misty1212):

start with \[12.5\times 2x=15(x+2)\] and solve for \(x\)

OpenStudy (astrophysics):

Ah, so this one requires a ratio to, like your last question, thanks @misty1212

OpenStudy (misty1212):

\[\color\magenta\heartsuit\]

OpenStudy (anonymous):

hold on im sloving it

OpenStudy (anonymous):

is the answer 6?

OpenStudy (anonymous):

@misty1212

OpenStudy (astrophysics):

Nope, you may have messed up somewhere, \[(12.5)(2x)=15x+30\]

OpenStudy (anonymous):

25x=15x+30

OpenStudy (astrophysics):

\[25x=15x+30\]

OpenStudy (astrophysics):

Yes

OpenStudy (astrophysics):

Keep going

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

10x=30?

OpenStudy (astrophysics):

Yup, one more step

OpenStudy (anonymous):

x=3?

OpenStudy (astrophysics):

Yes!

OpenStudy (anonymous):

ok thanks! i need help with a few more!
