2x-6x+9x+25=150+10x-35
Show the work

X=-18

Step-by-step explanation:

2x-6x+9x+25=150+10x-35

combine like terms

5x+25=115+10x

move Xs to one side

25=115+5x

sebstract 115 from 25

-90=5x

divide -90 by 5

x=-18

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
