Find two numbers whose difference is 8 but whose average is 13.

9 and 17

Step-by-step explanation:

let x and y be the 2 numbers , x > y , then

x - y = 8 → (1)

= 13 ( multiply both sides by 2 )

x + y = 26 → (2)

add both equations term by term to eliminate y

2x + 0 = 34

2x = 34 ( divide both sides by 2 )

x = 17

substitute x = 17 into (1) and solve for y

17 - y = 8 ( subtract 17 from both sides )

- y = - 9 ( multiply both sides by - 1 )

y = 9

The 2 numbers are 9 and 17

one set of data has more variation than the other. hope this !
