Thanks!
Yes, Chopsticks, after trying the way I described in my last response, I got the same answers you have. Thank you for your help! :-)

algebra
Wow... 1/2 of a ball. :-) I see what you were trying to get across... but our teacher never showed us a problem like this... so frustrating. I don't know if your ratio way is exactly right, but it is a good way to straighten out the info. Wait... I got something! Maybe it&...

algebra
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...

Algebra
The sum of Eric and Bob's weights is 9 times greater than the difference of their weights. The positive difference of their weights is also 240 pounds less than the sum. If Eric weighs less than Bob, find Bob's weight. I am not sure at all how to solve this, especially...

Oh, okay. Do you understand now?

Hey Melanii (nooni)! :-) It's me! Anyway, I figured this one out. Well, drwls actually did tell you what you were looking for... their weights. Tweedledee will weigh 121 pounds and Tweedledum will weigh 120 pounds. Here are the two equations as our teacher showed us: e + 2...

spanish
I know all of the spanish sports vocabulary, but I don't know how to put it in a sentence. For example, "I play tennis with a tennis racquet. We play golf with a golf ball. They play soccer with soccer balls." Thank you.

Algebra: factoring
I need to find the value of x. 9x^3 + 9x = 30x^2 It's confusing because apparently I have to do 9x^3 + 9x and then add the + 30x^2 to it, and then make it equal 0, so it ends up like this: 9x^3 + 9x + 30x^2 = 0 And afterward, I would factor it. How do you factor it? I'...

chemistry
What pressure would have to be applied to steam at 325°C to condense the steam to liquid water (ÄH vap = 40.7 kJ/mol)? Responses Dr bob please! Chemistry - GK, Friday, November 28, 2008 at 11:47pm Use the Clausius-Clapeyron Equation to calculate the vapor pressure at ...

Chem- Dr bob! or GK!
Calculate the energy that must be removed to convert substance X from a gas at 116°C to a solid -44.6°C. Assume X has a molar mass of 75.0 g/mol. ÄHvap 20. kJ/mol C(s) 3.0 J/g·°C ÄHfus 5.0 kJ/mol C(l) 2.5 J/g·°C bp 75°C C(g) 1.0 J/g&...
