Best ResponseYou've already chosen the best response.0Hmm it's not what i am looking for....i am looking for (a+b+c)/3...arithmetic average of a,b and c..thnx anyway :)

Best ResponseYou've already chosen the best response.0do we not have another equation? i only see two equations and 3 unknowns we need another equation if you a number that is known like because we can write the answer right now as (18+c)/3 or (32a)/3 we can also write it in terms of b

Best ResponseYou've already chosen the best response.0Well, since we will add them all up after all, we can choose any values if a,b and c that satisfy the two given equation \(a+b=18\) and \(a+c=14\). So choosing \(a=b=9\) would imply \(c=5\), then \((a+b+c)/3=23/3\).

Best ResponseYou've already chosen the best response.0(a+b)/2+(b+c)/2+(a+c)/2=9+8+7=24 2(a+b+c)/2=24 (a+b+c)/3=24/3=8 :)

Best ResponseYou've already chosen the best response.0ok so 24/3=8 is correct gj because we get a=8 b=10 c=6 so (8+10+6)/3=8

Best ResponseYou've already chosen the best response.0a+b=18, a+c=14 and b+c=16 Hence, 2a+2b+2c=18+14+16=48 Or, a+b+c=24 Therefore, (a+b+c)=24/3=8
