Answer:

x = -12

y = 3

Step-by-step explanation:

$1/2x + 6(x+15) = 12\\1/2x + 6x + 90 = 12\\6\frac{1}{2} x + 90 = 12\\6\frac{1}{2} x= -78\\x = -12$

$y = x + 15\\y = -12 + 15\\y = 3$

Mr. Erickson will be living in the forest

aliina [53]

$\huge{\boxed{60\ \text{ft}^{3}}}$

We will assume the tent is in the shape of a triangular prism.

The volume of a triangular prism can be found with the following formula, where $b$ is the width at the base, $h$ is the height, and $l$ is the length.

$V=\frac{1}{2}bhl$

Substitute in the known values.

$V=\frac{1}{2}*5*3*8$

Simplify — use multiplication.

$V=\frac{5}{2}*3*8$

$V=\frac{15}{2}*8$

$V=\frac{120}{2}$

Simplify — use division.

$V=\large{\boxed{60\ \text{ft}^{3}}}$

The volume — or in this case, the amount of living space — is $60\ \text{cubic feet}$ .
