Algebra.Com's Answer #336399 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! Write an equation for each statment: \n" ); document.write( ": \n" ); document.write( "I have $9.45 in quarters and dimes in my pocket. \n" ); document.write( ".10d + .25q = 9.45 \n" ); document.write( ": \n" ); document.write( "The number of dimes is 18 less than twice the number of quarters. \n" ); document.write( "d = 2q - 18 \n" ); document.write( ": \n" ); document.write( "In the 1st equation replace d with (2q-18) \n" ); document.write( ".10(2q-18) + .25q = 9.45 \n" ); document.write( ".2q - 1.8 + .25q = 9.45 \n" ); document.write( ".2q + .25q = 9.45 + 1.80 \n" ); document.write( ".45q = 11.25 \n" ); document.write( "q = \n" ); document.write( "q = 25 quarters \n" ); document.write( ": \n" ); document.write( "I know you can find the number of dimes now, check the total in the 1st equation\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " How many of each do I have in my pocket? \n" ); document.write( " |
