The avg. (arithmetic - mean) of a and b is ninety; the avg. (arithmetic mean) of a and c is 150; what is the total value of (b-c)/2?

You can't solve something like this you have one equation with two unknowns. Because arithmetic average of a and b is ((a+b)/2) and you said it's 90, but you don't know from this, what is a or b
And the same is is valid for c and d, of course.

StinkyPink · 01-18-2013, 11:57 AM

there is no D.... unless he is seeking the sum of D as to which I thought would be X

woj · 01-18-2013, 12:06 PM

you just subtract 2nd equation from the first...

(a+b)/2=90
(a+c)/2=150
-------------------
((a+b)-(a+c))/2=90-150
(a+b-a-c))/2=-60
(b-c)/2=-60

You may be dead on, or dead wrong. I am too old to remember these equations. If I had to guess though, I would say you were RIGHT!

this is correct, and I said it already a few posts up

Fuck, I didn't read it properly, in this case I agree with " d-null " it's -60

you are right, I thought it too simple to bother

a+b=180
a+c=300

a=180-b
a=300-c

180-b=300-c

-b=120-c

b=c-120

(b-c)/2

(c-120-c) /2

pornmasta · 01-18-2013, 12:47 PM

(a+b)/2=90
(a+c)/2=150

a+b=180
a+c=300

a=180-b
c+180-b=300

c-b=120
-120=b-c
-60=(b-c)/2

My math teachers would give us an F if we didn't "write it out".

And.... wait for it.... wait for it... most of us ARE simple. lmao

Reading this thread I see why so many people ask to explain what is the ratio column in our affiliate report and how it is calculated.

ilnjscb · 01-18-2013, 07:21 PM

(a+b)/2=90; (a+c)/2=150
(a+b)/2=((a+c)/2)-60
a/2 + b/2=a/2 + c/2 -60
b/2=c/2 -60
b/2-c/2=c/2-c/2-60
(b-c)/2=-60

Years and years ago there was a software you could feed the two starting equations to and it would do all the steps and writing it out for you. I think it ran on my Apple ][ (yes, showing my age) - anybody remember what it was called?
