joe has twice as many quarters than dimes in total joe has 9 dollars how many coins of each does joe have\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The coins together will add up to $9.00 yes?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So... let's make an equation using \"D\" for Dimes and \"Q\" for Quarters, but remember there are TWICE as many quarters as dimes. That will translate to.....\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "D(.10) + 2D(.25) = 9.00 <----Here is our equation....
\n" ); document.write( ".10D + .50D = 9.00 (see how we multiplied .10 times D and multiplied 2D times .25?)
\n" ); document.write( ".60D = 9.00 (added like terms)
\n" ); document.write( "D = 15 (divide both sides by .60)\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore you have 15 dimes. If you have twice as many quarters as those 15 dimes, then you have 2 times 15 which is 30 quarters.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Soooo, does this add up to 9.00? \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let's see: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "15 dimes equals: $1.50
\n" ); document.write( "30 quarters equals: $7.50
\n" ); document.write( "TOTAL: $9.00\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It works. I hope this helps.
\n" ); document.write( "
