What is the answer to 3×+9=42

x = 11

Step-by-step explanation:

from question 3x + 9 = 42

collect the like terms

3x =  42-9

3x = 33

divide both sides by 3

3x/3 = 33/3

x = 11

to check if your answer is correct, put 11 where you see x in the question.

3x + 9 = 42

3(11) + 9 =42

33+9 = 42

42 = 42proved

step-by-step explanation:

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
