You can set them equal to eachother
x+1=3x-19
solve for X
-3x both sides
-2x+1=-19
-1 both sides
-2x=-20
÷-2 both sides
x=10
y=10+1
y=11

Answer:
C.) cone Z and C.) cylinder Y
Step-by-step explanation:
The relationship between the volume of a cone and the volume of a cylinder with the same base is and height is that the volume of the cone is 1/3 the volume of the cylinder.
The formula for the volume of a cylinder is
V = πr²h
The formula for the volume of a cone is
V = 1/3πr²h
Let h be the height of cylinder Y. This means that the height of cone Z is 3h; plugging this into the formula, we have
V = 1/3πr²(3h) = πr²h
Answer:
B.7
Step-by-step explanation:
This one is pretty simple, just insert each number to find which one is true.
2(7)<18
14< 18 (true)
2(9) < 18
18< 18 (false because it said less than not less than or equal to)
2(36) < 18
72< 18 (false)
