Answer:

Step-by-step explanation:

Let's take one of the equations and solve for x. I'll take the first one.

Divide by 13.

Now replace x in the second equation.

Distribute -8

Break down the fraction.

Subtract 

Subtract 6y

Combine like terms;

Solve;

Keep solving;

Multiply by the negative reciprocal of the fraction next to y.

On the right side; 13 and 13 become 1. 300/30 = 30/3 = 10

After having found y, replace it in any of the equations to find x.

Answer: So if its a sphere the answer its 7238.2.
If its a cylinder the answer is 371.7.
If its a triangular shape the answer is
123.9.
The correct answer to this question is the fourth statement. <span> The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.</span>
