Answer:
<h3>A. y=-2x+3z+25</h3>
Step-by-step explanation:
Isolate the term of x and y from one side of the equation.
<u>To solve:</u>
<h3>2x+y-3z=25</h3>
<u>First, you have to subtract by 2x-3z from both sides.</u>
<u>Solve.</u>
- <u>Therefore, the correct answer is "A. y=-2x+3z+25".</u>

Answer:
$819
Step-by-step explanation:
First we find the area of the wall so we multiply 13ft x 9ft.
13ft x 9ft = 117ft
We know each square foot is equal to $7. So now we multiply 117 x 7 to get the total cost.
117 x 7 = $819
Answer:
Equation for the area of a circle- π r²
The 2 radiuses are 6 and 9.
6 squared is 36 and 9 squared is 81.
The smaller one is 36π and the larger one is 81π.
The difference between them is the area of the shaded region.
81π - 36π = 45π
Use 3.14 for π.
45 x 3.14 = 141.3 u²
Hope this helps!
