If twice the number, added to 3 is divided by the number plus 9, the result is three halves. Find the number

x=21

Step-by-step explanation:

(3+2x)/(x+9)=3/2

(x+9)(3+2x)=(3/2)(x+9)

3+2x=(3x+27)/2

2(3+2x)=3x+27

6+4x=3x+27

x=21

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
