Answer:

29.4 %

Step-by-step explanation:

The area of the sector is directly proportional to the angle subtending the arc.

Area of sector/area of circle = 106°/360° = 0.294

The area of the sector is 29.4 % the area of the circle, so

A point chosen at random will be in the shaded region 29.4 % of the time.

4x – 9 = 2x + 15 can someone explain the system used to answer this question

PSYCHO15rus [73]

The system is comprised of two processes
that go on at the same time:

   #1). Do what ever you want to, to get 'x'
   on one side of the equation, and
   everything else on the other side.
   #2). Whatever you do to one side of the equation,
   you must immediately do the same thing to the
   other side.

That's the system.

Here's how it works: (I can't believe you're in high school math
and you've never seen, studied, or practiced this before.)

You said that       4x - 9 = 2x + 15
and you need to find
what 'x' is.

Subtract 2x from each side: 2x - 9 =   15

Add 9 to each side:        2x =      24

Divide each side by 2 : x =   12 .
