Ten less than three times the sum of x and seven is twenty-six??

3(x + 7) - 10 = 26

3x + 21 - 10 = 26

3x + 11 = 26

3x = 15

x = 5

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

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
