An oil tank was 1/10 full then 280 gallons was delivered which made it 8/10 full. If x= the capacity of the oil tank, what equation can be used to find the capacity of the tank?
\n" ); document.write( ".
\n" ); document.write( "Let x = capacity of the oil tank
\n" ); document.write( ".
\n" ); document.write( "From:\"An oil tank was 1/10 full then 280 gallons was delivered which made it 8/10 full.\" we get:
\n" ); document.write( "(1/10)x + 280 = (8/10)x
\n" ); document.write( ".
\n" ); document.write( "Solving for x:
\n" ); document.write( "(1/10)x + 280 = (8/10)x
\n" ); document.write( "multiplying both sides by 10:
\n" ); document.write( "x + 2800 = 8x
\n" ); document.write( "2800 = 7x
\n" ); document.write( "400 gallons = x
\n" ); document.write( "
\n" ); document.write( "
\n" );
