You fill your cars gas tank when it is about 1/2 empty. The next week, you fill the tank a second time when it is about 3/4 empty. If you buy a total of 18 1/2 gal of gas on these two days, abput how many gallons does the tank hold?
\n" ); document.write( ".
\n" ); document.write( "Let x = amount (gallons) tank holds
\n" ); document.write( "then
\n" ); document.write( "(1/2)x + (3/4)x = 18.5
\n" ); document.write( "(2/4)x + (3/4)x = 18.5
\n" ); document.write( "(5/4)x = 18.5
\n" ); document.write( "5x = 74
\n" ); document.write( "x = 14.8 gallons\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
