(3/2)x - -4 =13 what is x?

x=6

Step-by-step explanation:

(3/2)x - -4 =13

(3x/2)+4=13

Make 3x/2 the subject

3x/2=13-4

3x/2=9

Cross multiply

3x=9(2)

Divide both sides by 3

3x/3= 9(2)/3

x=3(2)

x=6

To check if correct, substitute x for 6 in the equation. And both sides of the equation must be equal

(3/2)x - -4 =13

(3/2)6 - -4 =13

18/2+4=13

9+4=13

13=13

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
