X + y = 33
x - y = 9 Add the 2 equations together
---------------
2x = 42 Divide both sides by 2
x = 21
Use the original equation and plug 21 in for x, then solve.
x + y = 33
21 + y = 33
Subtract 21 from both sides
y = 12
One list had 21 items on it and the other list had 12 items on it.

Answer:
(2,-3)
x=2 y=-3
Step-by-step explanation:
2x+y=1 y=1-2x
3x+2y=0
3x+2(1-2x)=0
3x+2-4x=0
-x+2=0
-x=-2
x=2
2x+y=1
2(2)+y=1
4+y=1
y=-3
Answer:
Volume of Cylinder using Cavalieri's Principle is .
Step-by-step explanation:
Given that,
Area of cross-section of a solid cylinder is .
Height of solid is .
According to Question,
The Cavalieri's Principle : if two or more solid figures have same cross-sectional area at energy level and height is same then its volume is same.
So, Volume of Cylinder =
Substituting the given value we get,
Volume of cylinder =
Hence, Volume of Cylinder using Cavalieri's Principle is .
