Answer:
x = 2 and y = -2
Step-by-step explanation:
We must first eliminate the y-variable:
2x + 3y = -2
3x - 6y = 18
4x + 6y = -4
3x - 6y = 18
_________
7x = 14
x = 2
Since we know x=2, we plug that back into one of the original equations to find y:
2x + 3y = -2
2(2) + 3y = -2
4 + 3y = -2
3y = -6
y = -2
Therefore, x = 2 and y = -2
This means that when you write your equation you will have in x somewhere in it the X will be the number 2 or the number 3. hope thia helps good luck!
Answer:
1696.460033 u^3
Step-by-step explanation:
1. The volume formula for a cylinder is
.
2. The radius is half of the width, So r would be 6. (12/2=6)
3. (6)^2 is 36. (6x6)
4. The height is given, which is 15.
5. Plug these numbers into the equation. It should be

6. This gives you your answer of 1696.460033 u^3.
