Algebra.Com's Answer #679346 by josgarithmetic(39617)![]() ![]() ![]() You can put this solution on YOUR website! If A and B are their individual rates in WORK per DAYS, then this system describes the situation:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "SIMPLFICATIONS\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "18A+18B=1 \n" ); document.write( "- \n" ); document.write( "10A+10B+12B=1 \n" ); document.write( "10A+22B=1 \n" ); document.write( "- \n" ); document.write( " \n" ); document.write( "Solve this system for A and B, but you will want the reciprocal of A, if the question you want is, how much time does \"A\" need alone to do one piece of work. \n" ); document.write( " |
