A chemist has 2 alloys, 1 of which is 10% gold and 20% lead, and the other of which is 30% gold anf 35% lead. How many grams of each of the 2 alloys should be used to make an alloy that contains 63g of gold and 111g of lead? \n" ); document.write( "----------------- \n" ); document.write( "Gold Equation: 0.10x + 0.30y = 63 \n" ); document.write( "Lead Equation: 0.20x + 0.35y = 111 \n" ); document.write( "----------------------------------------- \n" ); document.write( "Use whatever method you know to solve this system to get: \n" ); document.write( "x = 450 grams (amt of the 1st alloy in the final mixture)\r \n" ); document.write( "\n" ); document.write( "y = 60 grams (amt of the 2nd alloy in the final mixture)\r \n" ); document.write( "\n" ); document.write( "============================================================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
