Algebra.Com's Answer #353252 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! You have 83 coins which consist of nickels and dimes that equal $6.95 how many of each do you have? \n" ); document.write( ": \n" ); document.write( "The no. of coins equation: \n" ); document.write( "n + d = 83 \n" ); document.write( "n = (83-d); use the form for substitution \n" ); document.write( ": \n" ); document.write( "The value equation \n" ); document.write( ".05n + .10d = 6.95 \n" ); document.write( "replace n with (83-d) \n" ); document.write( ".05(83-d) + .10d = 6.95 \n" ); document.write( "4.15 - .05d + .10d = 6.95 \n" ); document.write( ".05d = 6.95 - 4.15 \n" ); document.write( ".05d = 2.80 \n" ); document.write( "d = \n" ); document.write( "d = 56 dimes \n" ); document.write( ": \n" ); document.write( "You can find the number of nickels, check your solutions in the value equation \n" ); document.write( " |
