Answer:
Step 1: 14x − 21 = 1; Step 2: 14x = 22
Explanation:
7(2x−3)=1
Step 1: Simplify both sides of the equation
7(2x−3)=1
(7)(2x)+(7)(−3)=1(Distribute)
14x+−21=1
14x−21=1
Step 2: Add 21 to both sides
14x−21+21=1+21
14x=22
Step 3: Divide both sides by 14
14x / 14 = 22 / 14
x = 22 / 14: x = 11/7

Answer:
V = Bh = πr2h
Step-by-step explanation:
Answer:
18 π cm^2.
Step-by-step explanation:
The area of the whole circle = π r^2 = 81π cm^2.
Since there are 360 degrees in a circle the area of the shaded region =
80/360 * area of the circle.
This = 80/360 * 81 π
= 2/9 * 81 π
= 18 π
