Algebra.Com's Answer #219409 by sejackson91(8)![]() ![]() ![]() You can put this solution on YOUR website! first write out the words they give you as equations \n" ); document.write( "the difference of two numbers is 12 means that \n" ); document.write( "A - B = 12 if A and B are our two numbers \n" ); document.write( "then two fifths of the greater number is six more than one third of the lesser number \n" ); document.write( "the second part can be broken up to make it easier to understand \n" ); document.write( "say that A is the greater number \n" ); document.write( "two fifths is 2/5 \n" ); document.write( "so two fifths of the greater number is (2/5)A remember that in these word problems of means you need to multiply \n" ); document.write( "next this (2/5)A is 6 more than something so say that (2/5)A - 6 = this something \n" ); document.write( "the something is one third of the lesser number so it is (1/3)B \n" ); document.write( "finally: \n" ); document.write( "(2/5)A - 6 = (1/3)B \n" ); document.write( "now we need to find the two numbers using the two equations we wrote: \n" ); document.write( "A - B = 12 \n" ); document.write( "(2/5)A - 6 = (1/3)B \n" ); document.write( "looking at the first equation we see that A = 12+B \n" ); document.write( "we can substitute that into the second equation \n" ); document.write( "(2/5)(12+B) - 6 = (1/3)B \n" ); document.write( "(24/5) + (2/5)B - (30/5) = (1/3)B \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
