Algebra.Com's Answer #118490 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! the weight multiplied by the distance from the fulcrum is a quantity called the \"moment\" \n" ); document.write( "__ at equilibrium, the moments on either side of the fulcrum are equal\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "40(6)+30(x)=60(8) __ 240+30x=480 __ 30x=240 __ x=8 \n" ); document.write( " |
