Algebra.Com's Answer #373312 by josmiceli(19441) You can put this solution on YOUR website! let their weights = \n" ); document.write( "Mark's = \n" ); document.write( "Steve's = \n" ); document.write( "Joseph's = \n" ); document.write( "Tim's = \n" ); document.write( "Carl's = \n" ); document.write( "------------ \n" ); document.write( "To convert decimals, move decimal point \n" ); document.write( "2 places to the left \n" ); document.write( "given: \n" ); document.write( "(1) \n" ); document.write( "(2) \n" ); document.write( "(3) \n" ); document.write( "(4) \n" ); document.write( "----------- \n" ); document.write( "Normally you couldn't solve this for all \n" ); document.write( "their weights because there are 5 unknowns \n" ); document.write( "and only 4 equations. \n" ); document.write( "They only want the one who weighs the least, \n" ); document.write( "so I can find that. \n" ); document.write( "----------- \n" ); document.write( "(3) tells me Mark weighs more than Carl \n" ); document.write( "(4) tells me Carl weighs more than Joseph \n" ); document.write( "So far the order is \n" ); document.write( "Mark \n" ); document.write( "Carl \n" ); document.write( " Joseph \n" ); document.write( "Now substitute (1) into (3) \n" ); document.write( "(3) \n" ); document.write( "(3) \n" ); document.write( "(3) \n" ); document.write( "(3) \n" ); document.write( "So, Steve weighs more than Carl, but (1) \n" ); document.write( "says Mark weighs more than steve, so \n" ); document.write( "the order now is \n" ); document.write( "Mark \n" ); document.write( "Steve \n" ); document.write( "Carl \n" ); document.write( "Joseph \n" ); document.write( "------------ \n" ); document.write( "(2) says Tim weighs more than Joseph \n" ); document.write( "No matter where Tim fits in, Joseph Has \n" ); document.write( "to weigh the least \n" ); document.write( "Hope I got it \n" ); document.write( " |
