x + y + z = 140
OpenStudy (aripotta):
4x + 4y + 8z = 840?
OpenStudy (aripotta):
6x = y
OpenStudy (aripotta):
are those equations correct? :/
OpenStudy (aripotta):

Now, " six times as much linguine as it does macaroni. "
L = 6M
OpenStudy (aripotta):
yea, that's what my 6x = y is :)
OpenStudy (anonymous):
M + L + B = 140
->7M + B = 140 lbs
OpenStudy (aripotta):
WAIT what are you doing? :/ where did 7m come from?
OpenStudy (aripotta):
waaaaaaait what

4 * 7M + 8B = $ 6 * 140
28 M + 8B = 840
7 M + B = 140
OpenStudy (aripotta):
ok one sec. lemme work it out
OpenStudy (aripotta):
sorry, i'm trying to help someone and do my work at the same time :l not really working out, is it?
OpenStudy (aripotta):
i've found out x = 10, but that's how far i've gotten
OpenStudy (aripotta):
y = 60

70?
OpenStudy (anonymous):
Of course,
B = 140 - ( 10 + 60 ) =
OpenStudy (aripotta):
yup

thanks
