Solve the following system of equations using the substitution method.

Novay_Z [31]

X=2y
2x+5y=9

substitute the x=2y into the second equation
2(2y)+5y=9
multiple the 2y by 2. 4y+5y=9
combine like terms. 9y=9
divide the 9 out from both sides. y=1
plug the y back into the first equation
x=2(1)
multiply. x=2

your answer is: x=2
y=1

A box in the shape of a rectangular prism is approximately 9 inches long,has an equilateral triangle shaped base with side lengt

vfiekz [6]

Answer:

33.75 cubic inches of styrofoam can be placed inside the container.

Step-by-step explanation:

Based on given information, the volume of the prism ( $V$ ), in cubic inches, is determined by using this formula:

$V = \frac{1}{2}\cdot b\cdot h \cdot l$ (1)

Where:

$b$ - Base of the triangular face, in inches.

$h$ - Height of the triangular face, in inches.

$l$ - Length of the prism, in inches.

If we know that $b = 3\,in$ , $h = 2.5\,in$ and $l = 9\,in$ , then the volume of the prism is:

$V = \frac{1}{2}\cdot b\cdot h \cdot l$

$V = 33.75\,in^{3}$

33.75 cubic inches of styrofoam can be placed inside the container.

ololo11 [35]

Answer:

The answer is A

Step-by-step explanation:

Step 1: Use Cosine to find ∅

Cos∅= $\frac{4}{5}$

∅=Cos $^{-1}$ ( $\frac{4}{5}$ )

Therefore the answer is A
