-3(x+n)=x
solve for x

x = (-n/2)

Step-by-step explanation:

-3(x+n)=x      Problem:

-3x-n=x         Distributive property

-n=2x            Add 3x to both sides

2x=-n            Switch equation around to make it easier to look at

x= -n/2          Divide by 2 on each side

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
