2x + y = 5

x − 2y = 10

y = 5 − 2x

x − 2(5 − 2x) = 10

x − 10 + 4x = 10

5x − 10 = 10

<em>add 10 to each side</em>

<em>5x-10+10 = 10 + 10</em>

<em>5x=20</em>

5x = 0    <em>this is the error</em>

He needs to add 10 to each side

stealth61 [152]

Answer:

The height of the tent = 3 feet

Step-by-step explanation:

Question

Syrus is buying a tent with the dimensions shown below. The volume inside the tent is 36 feet^3. Syrus isn't sure if the tent will be tall enough for him to sit up inside. The tent is the shape of triangular prism whose length is 6 feet and width is 4 feet. What is the height of the tent?

Given:

Length of the tent = 6 feet

Width of the tent = 4 feet

Volume of the tent = 36 feet^3

To find the height of the tent.

Solution:

Since the ten is in shape of triangular prism, so the volume of traingular prism is given as:

V=\frac{1}{2}\times l\times w\times h

where l represents length, w represents width and h represents height of the prism.

Plugging in the know values of the dimension of the tent and the volume to find the height of the tent.

36=\frac{1}{2}\times 6\times 4\times h

Simplifying.

36=12h

Dividing both sides by 12.

\frac{36}{12}=\frac{12h}{12}

3=h

∴ h=3

Thus, the height of the tent = 3 feet

Is the enlargement or a reduction? Find the scale factor of the dilation.<br> Explain
malfutka [58]

Good evening ,

Answer:

In this case the dilation is a reduction (as you can see the image triangle is smaller than the original triangle)

and also the scale factor = OA’/OA = 2/6 = 1/3

since  -1 < 1/3 < 1 then it’s a reduction.

Step-by-step explanation:

Look at the photo below for more details (notice OA’ and OA).
