Andrew and john are both beatles fans. their respective collections share nine of the same albums. andrew has seventeen albums in his collection. six albums are in john's collection, but not andrew's. how many albums are in either andrew's or john's collection, but not both?

Answer is 14, look below for explanation.

Step-by-step explanation:

Andrew has 17 albums and John has 6 albums that are not in Andrew's.

They have 9 of the same albums.

The ones that Andrew ONLY has: 8

the ones that Andrew shares with John: 9

The one that John has alone: 6

the answer is 8+6 = 14

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

what is the original number? you forgot to add it.
