Solve. 2x + 7 ≥ 27 or 3 + 3x ≤ 30

x ≤ 9 or x ≥ 10

Step-by-step explanation:

2x + 7 ≥ 27

2x ≥ 20

x ≥ 10

or

3+ 3x ≤ 30

3x ≤ 27

x ≤ 9

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
