$\bf \begin{array}{ccllll}
ounces&doses\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
4&20\\
13&x
\end{array}\implies \cfrac{4}{13}=\cfrac{20}{x}$

solve for "x"

Answer:

D

Step-by-step explanation:

If there is a 2x2 matrix as $\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]$

The determinant is given by $\frac{1}{ad-bc}\left[\begin{array}{ccc}d&-b\\-c&a\\\end{array}\right]$

<em>Now, if we calculate the value of "ad - bc", we see that:</em>

$(-4)(-12)-(8)(6)=0$

We can't calculate the inverse, the inverse doesn't exist. The answer is D.
