9.4*
OpenStudy (pinklion23):
yeah that is what i said then the answer to that equation is 1.8
jagr2713 (jagr2713):
Ok now divide that by -8.4 what do we get?
OpenStudy (jhannybean):
ok.
so we have x + 1.8 = -8.4
Add -1.8 to both sides
OpenStudy (anonymous):

OpenStudy (jhannybean):
i didn't even solve it so how would that be possible :P
OpenStudy (pinklion23):
yeah so what first
OpenStudy (jhannybean):
change \(\sf 5\frac{1}{3}\) into fractional form. \[\sf \frac{(5\cdot 3)+1}{3}\]
OpenStudy (anonymous):
i think its 9 1/3
OpenStudy (pinklion23):
so that is the answer
