1. The rate, given that the distance is 200 feet and the time is x+3 seconds.
\n" ); document.write( "Distance = RatexTime
\n" ); document.write( "Rate = Distance/Time
\n" ); document.write( "\"R=200%2F%28x%2B3%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2. The perimeter of a rectangle, given that the length is x yards and the width is 10 yards shorter.
\n" ); document.write( "Perimeter is 2 times the length plus 2 times width.
\n" ); document.write( "\"P=2x%2B2%28x-10%29\"
\n" ); document.write( "\"P=4x-20\"\r
\n" ); document.write( "\n" ); document.write( "3. gwen sold her car on consignment for x dollars. the saleswoman's commission was 10% of the selling price and Gwen received $6570.
\n" ); document.write( "Gwen money = Selling price - Salewoman's commission
\n" ); document.write( "Gwen money = Selling price - 10%(Selling Price)
\n" ); document.write( "Gwen money = Selling price(1 - 10%)
\n" ); document.write( "\"6570=x%281-10%2F100%29\"
\n" ); document.write( "\"6570=x%280.90%29\"
\n" ); document.write( "\"x=6570%2F0.90\"
\n" ); document.write( "\"x=7300\"
\n" ); document.write( "
\n" );
