9 times a number increased
by 8 is the same as 50
more than 2 times the
number. Find the number

The number is 6.

Step-by-step explanation:

Firstly, we can make the unknown value as x which is much easier to find. Next, by reading the question, we can form an expression in terms of x :

9 × x + 8 = 50 + 2 × x

9x + 8 = 50 + 2x

Now, you can find the value of x by making x as a subject :

9x + 8 = 50 + 2x

9x - 2x = 50 - 8

7x = 42

x = 42/7

= 6

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
