Step-by-step explanation:
-12x = 84
/-12 /-12
x = -7
2x+4
/2. /2
X=2
I think that’s what your looking how to do
Height = 9 ft
Radius = Diameter/2 = 12/2 = 6 ft
Volume of a cone = 1/3πr²h
= 2/3 × 3.14 × 6 × 6 × 9
= 339.12 ≈ 339.1 cubic foot.
Answer:
x = 2
y = -1
Step-by-step explanation:
2x + y = 3
-2y = 14 - 6x
6x - 2y = 14
2x + y = 3 | ×3 |
6x - 2y = 14 | ×1 |
6x + 3y = 9
6x - 2y = 14
__________--
5y = -5
y = -5/5
y = -1
2x + y = 3
2x + (-1) = 3
2x = 3 + 1
2x = 4
x = 4/2
x = 2
