\n" );
document.write( "Hi, 
\n" );
document.write( "Note***convert these problems to how many pennys or cents (they are all done that way)
\n" );
document.write( "1)Let x represent the number of dimes, then (x+9)is the number of nickels
\n" );
document.write( "5(x+9) + 10x = 135cents
\n" );
document.write( "solve for x \r
\n" );
document.write( "\n" );
document.write( "2) Let x represent the number of dimes, then (2x+1)is the number of quarters
\n" );
document.write( "10x + 25(2x+1) = 505 cents
\n" );
document.write( "solve for x
\n" );
document.write( "60x + 25 = 505
\n" );
document.write( "60x = 480
\n" );
document.write( "x = 8 dimes and therefore (2*8+1) quarters Or 17 quarters
\n" );
document.write( "checking our answer
\n" );
document.write( "80 + 425 = 505cents Or $5.05 \n" );
document.write( "

\n" );
