Answer:

$|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

Step-by-step explanation:

You can use these Cramer's formulas to solve for x and y:

$x=\dfrac{|A_x|}{|A|},\\ \\y=\dfrac{|A_y|}{|A|},$

where

$|A|=\left|\begin{array}{cc}12&-13\\ \\17&-22\end{array}\right|\\ \\ \\|A_x|=\left|\begin{array}{cc}7&-13\\ \\-51&-22\end{array}\right|\\ \\ \\|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

So,

$|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

AleksandrR [38]

Answer:

Step-by-step explanation:

Grocery Store

12 mi / 3 cm = x / 2.5 cm Cross multiply

12 * 2.5 = 3 * x Multiply

30 = 3x Divide by 3

30/3 = x

x = 10 miles

Library

12 mi / 2 cm = x / 1.5 Cross multiply

12 * 1.5 = 2x

18 = 2x Divide by 2

18/2 = x

9 miles

The library is closer than the grocery store.
