Please help! ~Find the volume of the triangular prism~
12345 [234]

Answer:

23.04 m^2

Step-by-step explanation:

The volume of a prism is base * height. In the case of a triangular prism, you need to find the area of the base first (aka the triangle).

The area of a triangle is base * height / 2. Since we have the values for those we can substitute the values into the formula and solve.

2.4 * 3.6 / 2 = 3.84.

Now multiply that by height of the prism, which is 6, and we get 23.04 m^2.

Hope this helps!

Solve each system by elimination by multiplying both equations. eliminate y first. show all work.
Alex17521 [72]
First \mathrm{Multiply\:}10x-3y=18\mathrm{\:by\:}3:\quad 30x-9y=54
Then \mathrm{Multiply\:}6x-10y=-22\mathrm{\:by\:}5:\quad 30x-50y=-110
To get \begin{bmatrix}30x-9y=54\\ 30x-50y=-110\end{bmatrix}
So...
30x-50y=-110 \ \textgreater \  \begin{bmatrix}30x-9y=54\\ -41y=-164\end{bmatrix}
-41y=-164 \ \textgreater \  \mathrm{Divide\:both\:sides\:by\:}-41 \ \textgreater \  \frac{-41y}{-41}=\frac{-164}{-41}
To get y = 4.
\mathrm{For\:}30x-9y=54\mathrm{\:plug\:in\:} \:y=4 \ \textgreater \  30x-9\cdot \:4=54
\mathrm{Multiply\:the\:numbers:}\:9\cdot \:4=36 \ \textgreater \  30x-36=54 \ \textgreater \
Next \mathrm{Add\:}36\mathrm{\:to\:both\:sides} \ \textgreater \  30x-36+36=54+36 \ \textgreater \  \mathrm{Simplify} \ \textgreater \  30x=90
Finally \mathrm{Divide\:both\:sides\:by\:}30 \ \textgreater \  \frac{30x}{30}=\frac{90}{30} \ \textgreater \  x = 3
Therefore our solutions are y = 4, x = 3
