2(2y+10)=7y  1 this is the equation I came up with so far

y and x will be the same for the whole rectangle, so if you set up an equation where 1 variable equals some numbers and the other variable that should help, im working on the problem now myself

Neat puzzle! Drawing the diagram shows that x = 2y+10 and 2x = 7y1 With these 2 equations, you can solve for y, and figure out x

Yes, I can solve it. But the purpose of this board is to teach YOU how to solve it.

I have the equation set up I just need help solving

dave0616Best ResponseYou've already chosen the best response.1
well what are you equations?
 one year ago

dave0616Best ResponseYou've already chosen the best response.1
nope thats not it. remember that the top and bottom are equal, and the sides are equal. given that information, set up two equations

Can you give example I don't know how to do that
 one year ago

dave0616Best ResponseYou've already chosen the best response.1
ok, so we know that ab is the top and the equation is 2x, and we know that dc is the bottom, and the equation is 7y1. because it is a rectangle the top and bottom will be equal in size. so you can set the equations equal to each other: 2x=7y1. can you set up an equation for the sides?

dave0616Best ResponseYou've already chosen the best response.1
correct. now pick one of the equations and solve for one of the variables. i decided to start with the equation for the sides. since it is already equal to x, you can plug that entire equation into x in the other equation. so it will look like: 2(2y+10)=7y1 now solve for y, and post what you get so i can tell you if you are correct

Dude that's exactly what I said the first time

Thats the same equation I wrote and I said I'm having trouble solving it

alright man, well i didnt recognize that. im sorry, you dont need to get so snippy man, just tryin to help. ok ok ok well now we know where we are.
 one year ago

dave0616Best ResponseYou've already chosen the best response.1
ok first you have the equation: 2(2y+10)=7y1 Multiply 2 out: 4y+20=7y1 Collect the y's on one side 3y=21 divide by 3 y=7

chocodropa7Best ResponseYou've already chosen the best response.0
So for x do we plug it in one of the equations? If so which one?
 one year ago

dave0616Best ResponseYou've already chosen the best response.1
do you remember the equation we got for the top and bottom? plug what you got for y into the equation and solve for x

I'm just making sure I get the right answer man, I can't afford to get anything wrong. WORK ON YOUR PATIENCE (JERK)
 one year ago

dave0616Best ResponseYou've already chosen the best response.1
dude, you are the one being a jerk, from the beginnning you had no patience. im not just gonna spit you an answer. im gonna make you wait for it man. my patience? i have no idea where you think im not being patient

qweqwe123123123123111Best ResponseYou've already chosen the best response.1
RELAX GANG!!! Once you found that y = 7, all you had to do to find x is remember that: x = 2y+10 With that you would replace all the "y"s with "7" and figure it out: x = 2(7)+10 which is: x = 14+10 which is x = 24

chocodropa7Best ResponseYou've already chosen the best response.0
First I give you the right eqation then you say its wrong, I ask simply if x is 24 or 25 and you call me a jerk. If I didn't ask and would've put 25 I wouldve gotten a 0 for my grade so excuse me for asking

dave0616Best ResponseYou've already chosen the best response.1
i didnt realize it was the same equation man. my bad for not recognizing how you just spit out an equation without explaining how you got there. and you were the one who is like "i need an answer now now now" so w.e man.
