Algebra.Com's Answer #128318 by ptaylor(2198) You can put this solution on YOUR website! Let x=amount of time it takes Jan and Wade together to paint the room \n" ); document.write( "Together they paint at the rate of 1/x room per hour \n" ); document.write( "Jan paints at the rate of 1/8 room per hour \n" ); document.write( "Wade paints at the rate of 1/10 room per hour \n" ); document.write( "Together they paint at the rate of 1/8 + 1/10=5/40 + 4/40=9/40 room per hour \n" ); document.write( "So, our equation to solve is: \n" ); document.write( "(9/40)x=1 (1 room that is) multiply each side by 40 \n" ); document.write( "9x=40 divide each side by 9 \n" ); document.write( "x=4 4/9 hours to paint the room with both working together\r \n" ); document.write( "\n" ); document.write( "Another way: \n" ); document.write( "1/x = 9/40 multiply each side by 40x \n" ); document.write( "40=9x \n" ); document.write( "x=40/9 hours\r \n" ); document.write( "\n" ); document.write( "CK \n" ); document.write( "(1/8)*(40/9)+ (1/10)*(40/9)=1 (room) \n" ); document.write( "5/9 +4/9=1 \n" ); document.write( "9/9=1 \n" ); document.write( "1=1\r \n" ); document.write( "\n" ); document.write( "Does this help?----ptaylor \n" ); document.write( " |
