Can someone please explain this too me? There's probably some simple answer, but I'm unsure. I'm pretty sure it's 50, but anyways:

"In the figure above, A, B, and C are points on a number line. AB = BC. What is the value of x+y?"

So it should be A=C, and x+y=25... right?

>> No.5126104

>>5126075
The coordonate of B is 25, who the hell knows where are X and Y, they could be at 24/26 or 10000/10002

>> No.5126112

>>5126104
Read carefully.

Homework question, go away.

>> No.5126113

AB=BC=n

x+n=25
x=25-n

y-n=25
y=25+n

x+y=25-n+25+n=50

holy cockfiddles son, do you know what AVERAGING TWO NUMBERS means?

/sci/ is fucking awful at math apparently

No two numbers satisfy 25x = 25y while (0 < x < 25) and (y > 25)

>> No.5126174

Not a homework question.


SAT question.

Post solution or get back to spergging in your corner

>> No.5126299

>>5126266
the solution is already posted, you bonafide retard

>> No.5126327

>>5126299
is correct

>>5126158
This is the solution

>> No.5126345

25X = 25Y

=> X = Y

BUT ASSUMING THE NUMBER LINE IS POSITIVE GOING LEFT -> RIGHT, X CANNOT EQUAL Y AS X < Y

THEREFORE NO ANSWER

You're a fucking retard.The fucking answer is 50, fucking 50. Do you not fucking understand what AB = BC means? It says the length of line segment AB is equal to the length of line segment BC.

is correct.
