Algebra.Com's Answer #2245 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Let N = # of nickels. A nickel = $0.05 \n" ); document.write( "Let D = # of dimes. A dime = $0.10\r \n" ); document.write( "\n" ); document.write( "The # of nickels plus the # of dimes = 175 (The total number of coins) \n" ); document.write( "N($0.05) + D($0.10) = $11.90 (The total value of the coins)\r \n" ); document.write( "\n" ); document.write( "The equations you need are: \n" ); document.write( " N + D = 175 \n" ); document.write( "N($0.05) + D($0.10) = $11.90\r \n" ); document.write( "\n" ); document.write( "Solve this system of equations for N and D and you will have solved the problem.\r \n" ); document.write( "\n" ); document.write( "I got: N = 112 and D = 63 \n" ); document.write( " |
