Answer:

x = 12, y =

Step-by-step explanation:

Let x=# of Ornaments and y=# of boxes of candy. The system of equations is:

x + y = 15

1.5x + 3y = 27

And solve via elimination

1.5 x = 18

x = 12, y =3

Answer:

$\displaystyle 93,5\:in.^2 \approx A$

Step-by-step explanation:

$\displaystyle \frac{3\sqrt{3}}{2}a^2 = A \hookrightarrow \frac{3\sqrt{3}}{2}6^2 = A \\ \frac{3\sqrt{3}}{2}[36] = A; 54\sqrt{3}\:[or\:93,530743609...] \\ \\ \boxed{93,5 \approx A}$

Quadrilateral KLMN is a rectangle. The coordinates of L are L(1,-4) and the coordinates of M are M(3,-2) find the slopes of side

m_a_m_a [10]

We can start by finding the gradient of LM
$m= \frac{ y_{2}- y_{1} }{x_{2} - x_{1} } = \frac{-2--4}{3-1} = \frac{2}{2}=1$

Two perpendicular lines will meet the requirement $m_{1}$ × $m_{2}$ =-1
Two parallel lines have equal gradients

NM is perpendicular to LM, hence the gradient of NM is -1
KN is a line that is parallel to NM, hence the gradient is 1
KL is perpendicular to LM, hence the gradient of KL is -1
