"Tweedledum says: the sum of your weight and twice mine is 361 lbs. Tweedledee says: contrariwise, the sum of your weight and twice mine is 362 lbs if both are right how much do they weigh together?" i got this part, but the next part i can't figure out:...

just reposting :):) i still don't really get it. "Tweedledum says: the sum of your weight and twice mine is 361 lbs. Tweedledee says: contrariwise, the sum of your weight and twice mine is 362 lbs if both are right how much do they weigh together?" i got...

the sum of eric's and bob's weights is 9 times greater than the difference of their weights. the positive difference of their weights is also 240 lbs less than the sum. if eric weighs less than bob, find bob's weight. i can't find an equation for this. an...

what i would do is divide 30 by 2, which is 15. then, since they are 8 apart, find 15-4 and 15+4. those are the two numbers they are 8 apart and =30. hope this helps, mel

why did you repost?? look on your other one the answers are there

srry that was me above

a flat sheet of paper has more area that the air pushes against, more mass, than a crumpled up paper.

if you look on google it will help you. mel :)

do you mean that they can orbit forever? if so then no they can't.

no. i thought that is what their weights together were!!!??? :)

hey!! rachelle (loondsiy) :):):)

LOONDSI i tried this one. kinda. i don't think this is right but my equation was this: 6a+15=b -15 -15 6a=b-15 -b -b -15=6a-b -1(-15=6a-b) 15=(-6)a+b and then i guessed and checked... (-2,3) worked but that didn't help. now i'm stuck too. nooni

erg i still don't really get it. oh well

maybe it's 6a=b? and they are 15 min apart?

i kinda did ratios 5:2 =10 4:1 =7 8:8 =? so then 2 1/2:1 =5 2:1/2 =3 1/2 4:4 =?

yeah... i don't know about that equation though. i don't think 15 fits into it....

yes!! to check, just plug in the numbers and see if they fit. :)

yeah.........................

thanks chopsticks. yeah that makes sense... i'm gonna try it.

ok for "r" i got 1.388888888888888(cont.)

both are right. the line does have infinite solutions, so either way works. it really depends on what you think works best or how your teacher teaches it.

i reposted it btw ok? :):):) just so you know.

no, actually i'm in seventh grade. i'm taking algebra 1. :)

lol i just came on here because 1. i needed help w/ homework 2. my friend and i can work together here my home work is really annoying tonite. if you look under many of the algebra or algebra 1 topics by me or Rachelle you'll see why i'm here. :):):)
