Algebra.Com's Answer #595462 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! In one hour, Bill mows (1/2) of the lawn, and with Tom can mow (1/1.5) of the lawn.\r \n" ); document.write( "\n" ); document.write( "Together, they can mow, in one hour (1/2) + (1/x)=(1/1.5)\r \n" ); document.write( "\n" ); document.write( "Multiply everything by 6x to clear fractions.\r \n" ); document.write( "\n" ); document.write( "3x+6=4x \n" ); document.write( "x=6 hours. It takes Tom 6 hours to mow the lawn. In one hour the two mow (1/2)+(1/6)=2/3. In the next half hour, they mow (1/4)+ (1/12)=(1/3), that finishes it up. \n" ); document.write( " |
