\(\bf \begin{array}{cccccclllll}
\textit{something}&&\textit{varies directly to}&&\textit{something else}\\ \quad \\
\textit{something}&=&{\color{brown}{ \textit{some value}}}&\cdot &\textit{something else}\\ \quad \\
y&=&{\color{brown}{ n}}&\cdot&x
\\\hline\\
&& y={\color{brown}{ n }}x
\end{array}\\ \quad \\
y=10.5\qquad x=1.5\qquad y={\color{brown}{ n }}x\implies 10.5={\color{brown}{ n }}1.5\impliedby \textit{solve for "n"}\)

Answer 4

So C?

Answer 5

hmm well.. what did you get for "n"?

Answer 6

Eh i just guessed
