Please help me please

The value of x in terms of b is   x = -3/b

The value of x when b is 3 is    x = -1

Work Shown:

Let's isolate x

-2(bx - 5) = 16

bx - 5 = 16/(-2) ... dividing both sides by -2

bx - 5 = -8

bx = -8+5 ... adding 5 to both sides

bx = -3

x = -3/b ... dividing both sides by b

That wraps up the first part.

To answer the second part, we plug in b = 3 to get

x = -3/b

x = -3/3

x = -1

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 !
