During one particular week, the two cars went a combined total of 1725 miles, for a total gas consumption of 60 gallons. How many gallons were consumed by each of the two cars that week? \n" ); document.write( "
Algebra.Com's Answer #450522 by josgarithmetic(39618)![]() ![]() ![]() You can put this solution on YOUR website! Uniform Rates, based on fuel efficiency, units for rates being MILES PER GALLON. The basic relationship equation is r*v=d, where r is the fuel efficiency, v is the volume of fuel, d is the miles.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Create and fill information into a table: \n" ); document.write( "Let x=gallons of fuel used car 1 \n" ); document.write( "Let y=gallons of fuel used car 2\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Which Car__________rate(mgp)_________fuel volume(gallons)_________distance \n" ); document.write( "FirstCar___________35________________x____________________________35x \n" ); document.write( "SecondCar__________20________________y____________________________20y \n" ); document.write( "TOTAL_______________________________60____________________________1725\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The equations to use will be the system: \n" ); document.write( " \n" ); document.write( "and \n" ); document.write( " \n" ); document.write( "Creating and developing all that was the hard part.
