5x - 2(2x - 1) = 2(3x - 4)

X = 2

Step-by-step explanation:

5x-4x+2 = 6x-8

10 = 5x

2 = x

Steps:

1. First multiply the -2 on the left side to open the bracket, then multiply the 2 on the right side to open up the bracket

2. Bring all the x's to the right side(as 6x>5x-4x) and the number to the right side(to convert the -8 to +8 and add it with the +2)

3. then add up the sums on each side.

Left side: [+2 +8 = +10]

Right side: [6x +4x -5x = 5x]

4. then divide the whole equation by 5

Left side: [+10/5 = 2]

Right side: [5x/5 = 1x (or) x]

5. To be left with 2 = x (or) x = 2

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
