The solutions to the given equation containing absolute value term |3x-7| - 7 = x are 0 and 7.

<h3>What are the solutions to the given equation?</h3>

Given the equation in question;

|3x-7| - 7 = x

First, add 7 to both sides.

|3x-7| - 7 + 7 = x + 7

|3x-7| = x + 7

Next, remove the absolute value term, this creates a ± on the right side of the question.

|3x-7| = x + 7

3x-7 = ±( x + 7 )

The complete solution is the result of both the negative and positive portions of the solution.

For the first solution, use the positive of ±.

3x-7 = ( x + 7 )

3x - 7 = x + 7

3x - x = 7 + 7

2x = 14

x - 14/2

x = 7

For the second solution, use the negative of ±.

3x-7 = -( x + 7 )

3x-7 = -x - 7

3x + x = -7 + 7

4x = 0

x = 0/4

x = 0

Therefore, the solutions to the given equation containing absolute value term |3x-7| - 7 = x are 0 and 7.

$V = \pi r^25$

Plug in the values

r = 4 ; h = 3

$V= \pi *4^2*3

V = 3.14 * 16 * 3

V = 150.72$

So approximately 150.7
