Algebra.Com's Answer #139828 by dukesmart(20)![]() ![]() ![]() You can put this solution on YOUR website! Let put x= number of dimes then we create the equation as follows:\r \n" ); document.write( "\n" ); document.write( "(10/100) x + (x+8)* (1/4) = 5.50 ...... (1) \n" ); document.write( " (note: 10/100= 1 dime, 1/4= quarter) \n" ); document.write( "solve this equation you will have the answer. \n" ); document.write( " \n" ); document.write( "Let multiply the equation (1) to 4, the (1) will become: \n" ); document.write( "(4/10) x +x+8 = 22 ( time the equation to 10) \n" ); document.write( "therefore : ====> 4x+10x+80= 220 \n" ); document.write( "therefore : 14x= 220-80 \n" ); document.write( " 14x=140 ======> x=10 dimes and x+8= 10+8 =18 quarters \n" ); document.write( "we have 10 dimes and 18 quarters \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( " |
