Answer:

Step-by-step explanation:

The purple circle, not ring is pi 7 squared = 153.93804

Then subtract the smaller circles area (pi 4 squared) = 153.9... - 103.6725576 =

50.2654824

Purple ring is 50.2654824

The entire circle is 4+3+3 (10) squared times pi = 314.1592654

( 50.2654824 / 314.1592654 ) x 100 = 15.999999998 %

5x+8=9x+12 helpppppp
Marina CMI [18]

Hi there! :)

Answer:

\boxed{X=-1}

<u><em>*THE ANSWER MUST HAVE  A NEGATIVE SIGN!*</em></u>

Step-by-step explanation:

First, you subtract by 8 from both sides of an equation.

5x+8-8=9x+12-8

Subtract.

12-8=4

5x=9x+4

Then, you subtract by 9x from both sides of an equation.

5x-9x=9x+4-9x

Simplify by equation.

-4x=-4

Divide by -4 from both sides of an equation.

-4x/-4=-4/-4

Divide by the numbers from left/right.

-4/-4=-1

\boxed{X=-1}, <em>is the FINAL/CORRECT ANSWER! :)</em>

<em>Have a nice day! :)</em>

<em>:D</em>

<em>-Charlie</em>

<em>Thank you!</em>
