You can put this solution on YOUR website!
The first question is a dilution. You are adding a material which contains zero amount of the solute to be diluted.\r

\n" ); document.write( "\n" ); document.write( "Second question is two-part mixture for known amount of resulting mixture. You can do all in one single variable if you want.
\n" ); document.write( "y, the gallons volume of the 10%
\n" ); document.write( "10-y, the volume of the 40%
\n" ); document.write( "-
\n" ); document.write( " $\"%2810y%2B%2810-y%2940%29%2F10=20\"$ \r
