20% solution, 50 ml. to be made using 10% and 50% solutions.
\n" ); document.write( "How much of each?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "20 is closer to 10 than it is to 50. Most of the resulting solution will be from the 10% solution.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "v of the 50%
\n" ); document.write( "50-v of the 10%
\n" ); document.write( " $\"50v%2B10%2850-v%29=20%2A50\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"50v-10v%2B10%2A50=20%2A50\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%2850-10%29v=20%2A50-10%2A50\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"v=50%28%2820-10%29%2F%2850-10%29%29\"$ ---------See how the given values correspond.\r
\n" ); document.write( "\n" ); document.write( " $\"v=50%281%2F4%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"v=12%261%2F2\"$ ----------the ml. of 50% solution to use. \n" ); document.write( "

\n" );
