In the parking lot of a truck stop there were six more cars than 18 wheel trucks. There were 134 wheels in the parking lot How many cars and trucks were there?
\n" ); document.write( "Let the number of 18 wheel trucks be: x
\n" ); document.write( "Then the number of cars is: x+6
\n" ); document.write( "There are 18 wheels per truck: 18x
\n" ); document.write( "There are 4 wheels per car: 4(x+6)
\n" ); document.write( "If we add the number of wheels together we get: 134
\n" ); document.write( "Problem to solve:
\n" ); document.write( "18x+4(x+6)=134
\n" ); document.write( "18x+4x+24=134
\n" ); document.write( "22x+24=134
\n" ); document.write( "22x+24-24=134-24
\n" ); document.write( "22x=110
\n" ); document.write( "22x/22=110/22
\n" ); document.write( "x=5
\n" ); document.write( "The number of trucks: x=5
\n" ); document.write( "The number of cars: x+6=5+6=11
\n" ); document.write( ":
\n" ); document.write( "Sanity check, if you had 5 18 wheelers and 11 cars, would you have 134 wheels?
\n" ); document.write( "5(18)+11(4)=134
\n" ); document.write( "90+44=134
\n" ); document.write( "134=134 Seems reasonable.
\n" ); document.write( "Happy Calculating!!! \n" ); document.write( "
