Answer:

62.83 in

Step-by-step explanation:

C is circumference

r is the radius

We sum up both, given first one radius is 2 and second one radius is 8, so we have:

The length of the belt should be around 62.83 in

Hi again!

|2x - 3| - 1 > 4

|2x -3| > 4 + 1

|2x -3| > 5

Now let's solve the absolute value

We know either 2x -3 >5 or 2x -3<-5

Let's solve the first possibility

2x - 3 > 5

2x > 5+ 3

2x > 8

x > 8/2

x> 4

Now solve the second possibility

2x - 3 < -5

2x < -5 + 3

2x < -2

x < -2/2

x< -1

Thus the correct answer is x > 4 or x < -1

I used an online graphing calculator

I hope this helps again!
