RATES in POOL per HOUR
\n" ); document.write( "hose1, \"1%2F12\"
\n" ); document.write( "hose2, \"1%2F%28x%2B2%29\"
\n" ); document.write( "hose1&2, \"1%2Fx\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Careful reading the description will give the right understanding for transcribing the rates.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The rate for the two hoses combined is the sum of the rates of the two hoses. The equation representing this is \"highlight_green%281%2F12%2B1%2F%28x%2B2%29=1%2Fx%29\".
\n" ); document.write( "LCD is \"12x%28x%2B2%29\", so ....\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"12x%28x%2B2%29%281%2F12%2B1%2F%28x%2B2%29%29=12x%28x%2B2%29%2Fx\"
\n" ); document.write( "\"x%28x%2B2%29%2B12x=12%28x%2B2%29\"
\n" ); document.write( "\"x%5E2%2B2x%2B12x=12x%2B24\"
\n" ); document.write( "\"x%5E2%2B2x=24\"
\n" ); document.write( "\"x%5E2%2B2x-24=0\"
\n" ); document.write( "FACTORABLE
\n" ); document.write( "\"%28x-4%29%28x%2B6%29=0\"
\n" ); document.write( "\"highlight%28x=4%29\"-----hose 1 and 2 together fill the pool in 4 hours.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hose2 needs \"x%2B2=4%2B2=highlight%286%29\"------ 6 hours to fill the pool.
