Algebra.Com's Answer #260443 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Let x = the number of years when the two trees will be the same height. \n" ); document.write( "For the 2ft tree, you can express its height in x years as: \n" ); document.write( "2+1(x) \n" ); document.write( "And for the 6ft. tree... \n" ); document.write( "6+0.5(x) \n" ); document.write( "So you need to find the value of x that would make these equal. \n" ); document.write( "2+x = 6+0.5x Subtract 0.5x from both sides. \n" ); document.write( "2+0.5x = 6 Now subtract 2 from both sides. \n" ); document.write( "0.5x = 4 Finally, divide both sides by 0.5 \n" ); document.write( "x = 8 \n" ); document.write( "So in 8 years, the two trees will be the same height. \n" ); document.write( " |
