Algebra.Com's Answer #100846 by ptaylor(2198)![]() ![]() You can put this solution on YOUR website! Let x=Sandy's weight \n" ); document.write( "Then 209-x=White Ear's weight \n" ); document.write( "Sport weighs 223-(209-x)\r \n" ); document.write( "\n" ); document.write( "And we are told that Sandy and Sport weigh 216 g together, so our equation to solve is:\r \n" ); document.write( "\n" ); document.write( "x+223-(209-x)=216 get rid of parens\r \n" ); document.write( "\n" ); document.write( "x+223-209+x=216 simplify \n" ); document.write( "2x+14=216 subtract 14 from each side \n" ); document.write( "2x+14-14=216-14 collect like terms\r \n" ); document.write( "\n" ); document.write( "2x=202 divide both sides by 2 \n" ); document.write( "x=101 g------------------------------Sandy's weight \n" ); document.write( "209-x=209-101=108 g---------------------White Ear's weight \n" ); document.write( "223-(209-x)=223-209+101=115 g-------------Sport's weight\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "CK\r \n" ); document.write( "\n" ); document.write( "Sandy and White Ears: \n" ); document.write( "101+108=209 \n" ); document.write( "209=209 \n" ); document.write( "White Ears and Sport: \n" ); document.write( "108+115=223 \n" ); document.write( "223=223 \n" ); document.write( "Sandy and Sport: \n" ); document.write( "101+115=216 \n" ); document.write( "216=216\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hope this helps---ptaylor\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
