How do you solve
-178=-5x+4(-4x-13)

x = 6

Step-by-step explanation:

-4x - 13  =   -1 • (4x + 13)

 -178 -  (-5x +  -4 • [4x + 13] )  = 0

  21x - 126  =   21 • (x - 6)

 21 • (x - 6)  = 0

x-6 = 0  

x = 6

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

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
