Algebra.Com's Answer #203317 by scott8148(6628) You can put this solution on YOUR website! time equals distance divided by rate\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(60 / x) + (18 / (x - 5)) = 3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "multiplying by x(x - 5) ___ 60x - 300 + 18x = 3(x^2 - 5x)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "0 = x^2 - 31x + 100\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "use quadratic formula to find x\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "this canoe must have a motor on it... \n" ); document.write( " |
