**Math**

sorry my computer messed up. my name is not "Anonymous"

**Algebra 1**

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. any help...

**Algebra 1**

i got (rounded) 1.4 and 1.4

**Algebra 1**

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

**Algebra 1**

5 green balls and 2 red balls together weigh 10 pounds, and 1 green ball and 4 red balls together weigh 7 pounds. If all red balls weigh the same amount and all green balls weigh the same, then what is the weight of 8 red and 8 green balls together? I'm not sure at all how...

**math**

i just did too. :)

**math**

sorry 5.4.3?

**math**

hi rachelle did you get number 5.3.4 yet?

**math**

good luck to you too, and no problem :)

**math**

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. :):):)

**math**

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

**math**

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.

**math**

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

**Algebra**

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

**Algebra**

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

**Algebra**

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

**Algebra 1**

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

**Algebra 1**

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

**Algebra 1**

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 this ...

**algebra**

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

**algebra**

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

**algebra**

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 =?

**Algebra**

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

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

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

**motion and projection**

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

**Math**

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

**Math**

thanks :)

**Math**

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

**Algebra1**

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

**Algebra1**

srry that was me above

**Algebra1**

"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: "...
