Algebra.Com's Answer #764024 by Theo(13342)![]() ![]() You can put this solution on YOUR website! j = number of peas that julia has. \n" ); document.write( "v = number of peas that vlada has.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "j/v = 3/2 \n" ); document.write( "solve for j to get j = 3/2 * v\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "after julia gave vlada 15 peas, julia still had 10 more peas than vlada. \n" ); document.write( "equation for that is: \n" ); document.write( "j - 15 = (v + 15) + 10. \n" ); document.write( "combine like terms to get j - 15 = v + 25. \n" ); document.write( "add 15 to both sides of this equation to get j = v + 25 + 15. \n" ); document.write( "combine like terms to get j = v + 40.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "in the equation of j = 3/2 * v, replace j with v + 40 to get v + 40 = 3/2 * v. \n" ); document.write( "subtract v from both sides of this equation to get 40 = 3/2 * v - v \n" ); document.write( "simplify to get 40 = 1/2 * v \n" ); document.write( "multiply both sides of this equation by 2 and solve for v to get v = 80.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "you have v = 80 \n" ); document.write( "you have j = 3/2 * v. \n" ); document.write( "replace v with 80 to get j = 3/2 * 80 \n" ); document.write( "solve for j to get j = 120.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "you have j = 120 and v = 80 \n" ); document.write( "j/v = 120/80 = 3/2, which confirms the original ratio is correct.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "julia had 120 peas at first. \n" ); document.write( "this is your solution.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "to confirm the rest of the probelm, julia gives vlada 15 peas. \n" ); document.write( "now julia has 105 and vlada has 95. \n" ); document.write( "julia still has 10 more peas than vlada. \n" ); document.write( "the rest of the problem is confirmed to be true.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
