Write a system of two equations using x and y to represent the following problem. A chemist is mixing two solutions together.
The chemist wants 100 gallons when complete. He is mixing a 24% solution with a 50% solution to get a 36% solution. How many gallons of each will he use?

Best ResponseYou've already chosen the best response.0call the amount of 50% solution x and then the amount of 36% solution is 100x

Best ResponseYou've already chosen the best response.0oops let me start again. call the amount of 50% solution x and the amount of 24% solution is then 100x

Best ResponseYou've already chosen the best response.0so \[.5x+.24(100x)=.36\times 100=36\]

Best ResponseYou've already chosen the best response.0this is what you need to solve. \[.5x+24.24x=36\] \[.26x+24=36\] \[.26x=12\] \[x=\frac{12}{.26}=46.15\] rounded

Best ResponseYou've already chosen the best response.0but if i would read correctly it only says "wrote two equations" the first would be \[x+y=100\] and the second would be \[.5x+.24y=.6\]

Best ResponseYou've already chosen the best response.0rather \[.5x+.24y=36\]

Best ResponseYou've already chosen the best response.0it doesn't say to solve them does it?

Best ResponseYou've already chosen the best response.0x+y = 100 .24x + .5y = .36 * 100

Best ResponseYou've already chosen the best response.0Yea i do need to solve them. i can prolly do that on my own tho.... :P retaking assignments from the begining of the year >.< Dont remember a thing

Best ResponseYou've already chosen the best response.0if you want to solve it a systems you have \[x+y=100\] \[.5x+.24y=36\]

Best ResponseYou've already chosen the best response.0multiply the bottom equation by 2 and the x's will drop out

Best ResponseYou've already chosen the best response.0\[x+y=100\] \[x.48y=72\]

Best ResponseYou've already chosen the best response.0dude, thats weird. let y = 100  x and substitute that into the second equation,

anonymous

Best ResponseYou've already chosen the best response.0add them and the x's drop out to get one equation in y \[.52y=28\] \[y=\frac{28}{.52}=53.846\] rounded

Best ResponseYou've already chosen the best response.0Naw he is doing elimination, thats substitution... i suck at substitution.. so go ahead and do elimination.. lol

Best ResponseYou've already chosen the best response.0cantorset first line i used 100x for y. but what is odd is that usually these problems are cooked up to give nice integer answers. this one is not.

Best ResponseYou've already chosen the best response.0unless my arithmetic is wrong. i got two ugly decimal answer. it is 50%, 24% and 36% yes?

anonymous

Best ResponseYou've already chosen the best response.0i trust your work , but first you want to multiply both sides to remove the decimal, if youre doing elimination

anonymous

Best ResponseYou've already chosen the best response.0for the second equation, multiply both sides by 100 first

Best ResponseYou've already chosen the best response.0you try it and see if you don't get something ugly. maybe i made a mistake. really please try it.

Best ResponseYou've already chosen the best response.0still get \[x=\frac{12}{.26}=\frac{1200}{26}=46.153846...\]

Best ResponseYou've already chosen the best response.0still get x=46.15 rounded making y = 53.85 rounded
