Suppose a is directly proportional to b, but inversely proportional to c. If c when b = 9 and c =5, then what is c when b=3?
What is c when b=3?
Hello Guest!
\(a:b=c:a\\ a^2=bc\\ a:9=5:a\\ a^2=45\\ bc=45\\ 3c=45\\ c=15\\ \color{blue}c=15\ when\ b=3 \)

$I \ don't \ like \ you \ asinus \ \begin{vmatrix} dum&dum&dumb \\ dum&dum&dumb \\ dum&dum&dumb \end{vmatrix}$
I'm sorry, but there's nothing that can be done.
Nice one Asinus!!!!
