Can you solve for C using the formula?
hartnn (hartnn):
ite Centigrade to faranheit conversion
hartnn (hartnn):
sure, i can,
can u ?
OpenStudy (anonymous):
No thats why I asked, I need help

subtract 32 from both sides, what u get ?
OpenStudy (anonymous):
\[F- 32 = 9\div5C\]
hartnn (hartnn):
right, now can u flip the fraction?
like if a/b=c/d
then
b/a=d/c
OpenStudy (anonymous):
\[1\div F-32 = 5\div 9C \] is that correct?
hartnn (hartnn):
just don't forget to keep brackets
1/(F-32)=5C/9

Okay, do I cross multiple now?
hartnn (hartnn):
now you can multiply both sides by 9/5
so that you isolate C on right side
OpenStudy (anonymous):
when I multiply 9/5 by both sides, do I cross multiple or multiply numerator by numerator and denominator by denominator?
OpenStudy (anonymous):
multiply*
hartnn (hartnn):
(9/5)(1/F-32) = 5C/9 * 9/5

so whats the final answer?
hartnn (hartnn):
on right side, u get only C
on left u get \(\large \frac{9}{5(F-32)}\)
hartnn (hartnn):
thats your final answer
