ikadub [295]

Answer:

$\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:x=-2,\:y=2}$

Step-by-step explanation:

$\begin{bmatrix}-7x-6y=2\\ 7x+4y=-6\end{bmatrix}$

$\mathrm{Substitute\:}x=-\frac{2+6y}{7}$

$\begin{bmatrix}7\left(-\frac{2+6y}{7}\right)+4y=-6\end{bmatrix}$

$\begin{bmatrix}-2-2y=-6\end{bmatrix}$

$\mathrm{For\:}x=-\frac{2+6y}{7}$

$\mathrm{Substitute\:}y=2$

$x=-\frac{2+6\cdot \:2}{7}\\\\x=-2$

Volume of a Rectangular Prism: V=lwh

l=50 cm
w= 30cm
h= 40 cm

Step 1: 50×30×40= 60,000

The volume of the tank is 60,000 cubic centimeters

The water reaches a height of 28 centimeters, or 2142.9 cubic centimeters per centimeter.

Step 2: 35× 2142.9= 75001.5 cubic centimeters

Step 3) 75001.5- 60,000= 15001.5 CUBIC CENTIMETERS ARE NEEDED TO FILL THE REST OF THE TANK TO A HEIGHT OF 35 CENTIMETERS

Hope this helps!
