If JK=6r, KL=3r, and JL=27, what is the value of r? Well i some how got 17, i did 6r+3r+27=180 and got r=17. But thats not in the choices. What did i do wrong?

@skate-4-life270 Did i set this up wrong?

OpenStudy (anonymous):

let me see

OpenStudy (anonymous):

were is the r in the picture?

OpenStudy (briensmarandache):

if jl is the whole line then its 6r + 3r =27

OpenStudy (anonymous):

oh nvm i just saw it

OpenStudy (anonymous):

I dont see r..there is no r in the picture

OpenStudy (briensmarandache):

so your solving 9r=27

OpenStudy (anonymous):

oh ok @briensmarandache i will try that

OpenStudy (anonymous):

ik its in the equation

OpenStudy (anonymous):

yeah so subtract 9 from 27

OpenStudy (anonymous):

Awesome so its R=3!

OpenStudy (briensmarandache):

yup @nevvy217

OpenStudy (briensmarandache):

no @skate-4-life270

OpenStudy (anonymous):

oh yeah sorry i just woke up you divide 9 from 27

OpenStudy (briensmarandache):

@skate-4-life270 9r is multiplication so you would you the opposite to both sides to get rid of it, thus, divide by 9

OpenStudy (anonymous):

yeah

OpenStudy (briensmarandache):

cool cool, lol i had some of those moments this morning
