If a + b = 8, b + c = 9, and c + a = 11, what is the average of a, b and c ? How to find average in such situation?

OpenStudy (usukidoll):

why is the denominator 3? does it have something to do with the number of equations involved? or something else?

OpenStudy (usukidoll):

I understood what was going on until the (a+b+c)/3 so if a+b+c =14 is our average 14/3?

OpenStudy (maheshmeghwal9):

yes

OpenStudy (usukidoll):

ah cool :)

OpenStudy (anonymous):

Thank you @maheshmeghwal9 :) @UsukiDoll what I understand about 2 is that a,b and c are occurring twice so adding them will give (2a + 2b + 2c) taking out common "2" will give 2(a + b + c) :D

OpenStudy (usukidoll):

yeah that's correct :)

OpenStudy (anonymous):

hihi I'm so smart :3 LOL jk

OpenStudy (usukidoll):

OpenStudy (anonymous):
