15 times a number is decreased by eight, the result is 17. find the number

the number is one

work:

let's analyze the question.

15 times a number is..

so, right away we have 15n.

decreased by eight...

we are subtracting 8, so 15n - 8

...the result is 17.

so, 15n - 8 will equal 17.

Find the number.

now, we solve for n.

15n - 8 = 17 (add 8 to both sides)

15n = 15 (divide both sides by 15)

n = 1

so, the number is one. hope this helps, have a great day!

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

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
