b= 14a/5
OpenStudy (anonymous):
I cross multiplied because it's a proportion,
9a = 5(b-a)
OpenStudy (anonymous):
@AriPotta can you help me? I'll give you a medal :)
OpenStudy (aripotta):
after cross-multiplying, you wanna distribute the 5
OpenStudy (anonymous):
9a=5b-5a
14a=5b

there's no multiple choice for this one :/
OpenStudy (aripotta):
hmm ok
OpenStudy (aripotta):
eh i'm not exactly sure how to do it
OpenStudy (aripotta):
OH
OpenStudy (aripotta):
so a = 5 and if b - a = 9 then b - 5 = 9 and b = 14

so a/b = 5/14
OpenStudy (aripotta):

OpenStudy (anonymous):
