Algebra.Com's Answer #361097 by TutorDelphia(193)![]() ![]() You can put this solution on YOUR website! I like doing this problems in terms of pennies rather than dollars. \n" ); document.write( "So a dime is worth 10 and quarter is worth 25. That gives me this equation: \n" ); document.write( "10d+25q=515 \n" ); document.write( "He has 8 more quarters than dimes can be written as: \n" ); document.write( "d+8=q \n" ); document.write( "This is already solved for q so I can sub in d+8 for q since they have equal values \n" ); document.write( "That gives me: \n" ); document.write( "10d+25(d+8)=515 \n" ); document.write( "Distribute the 25 \n" ); document.write( "10d+25d+200=515 \n" ); document.write( "Combine like terms and subtract 200 from both sides \n" ); document.write( "35d=315 \n" ); document.write( "Divide by 35 \n" ); document.write( "d=9 \n" ); document.write( "Sub in 9 for d \n" ); document.write( "9+8=q\r \n" ); document.write( "\n" ); document.write( "q=17\r \n" ); document.write( "\n" ); document.write( "If you need more help, just let me know.\r \n" ); document.write( "\n" ); document.write( "Thanks,\r \n" ); document.write( "\n" ); document.write( "Adam \n" ); document.write( " |
