Answer:
x=2
Step-by-step explanation:
x = 7 – 3y
2(7 – 3y) + 4y = 8
14 – 6y + 4y = 8
14 – 2y = 8
–2y = –6
y = 3
x + 3(3) = 7

Answer:
Step-by-step explanation: x+4-5=y
Answer:
42,10
Step-by-step explanation:
let the numbers be x and y and x>y
x+2y=62
3x-y=116
multiply by 2
6x-2y=232
add the first
7x=294
x=42
from first
42+2y=62
2y=62-42=20
y=20/2=10
Given:
Cone shape: radius = 24 cm ; height = 6cm
Cylinder: radius = 16cm
We need to find the volume of each shape.
Volume of a cone = π r² h/3 = 3.14 * 24² * 6/3 = 3.14 * 576 * 2 = 3,617.28
Volume of a cylinder = π r² h
3,617.28 = 3.14 * 16² * h
3,617.28 = 3.14 * 256 * h
3,617.28 = 803.84 h
3,617.28 / 803.84 = 803.84h/803.84
4.5 = h
The height of the cylinder is 4.5cm
