Algebra.Com's Answer #664026 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! x=number of hours Ryan takes; x+1=number of hours Eric takes \n" ); document.write( "In 1 hour Ryan fills 1/x of the orders \n" ); document.write( "in 1 hour Eric fills 1/(x+1) of the order \n" ); document.write( "Together, it takes them 4 hours \n" ); document.write( "(1/x)+(1/x+1)=(1/4); in 1 hour, they both do 1/4 of the whole project. \n" ); document.write( "multiply through by 4x(x+1) \n" ); document.write( "4(x+1)+4x=(x)(x+1) \n" ); document.write( "4x+4+4x=x^2+x \n" ); document.write( "0=x^2-7x-4 \n" ); document.write( "x=(1/2)((7+/-sqrt(65); sqrt (65)=8.06 \n" ); document.write( "use positive root. \n" ); document.write( "x=(1/2)(15.06)=7.53 hours for Ryan and 8.53 hours for EricANSWER \n" ); document.write( "in 4 hours, Ryan does 4/7.53 and Eric does 4/8.53, and those are 0.531 and 0.469 with the sum 1.00 of the project. \n" ); document.write( " |
