document.write( "Question 762578: The ratio of the number of yellow balls to the green balls in a bag was 4:7. When 6 green balls were removed and 3 more yellow balls were added to the bag, there were as many yellow balls as green balls. How many yellow balls and green balls were in the bag originally? \n" ); document.write( "
Algebra.Com's Answer #464070 by ramkikk66(644)![]() ![]() ![]() You can put this solution on YOUR website! Ratio of yellow to green initially is 4:7.\r \n" ); document.write( "\n" ); document.write( "Assume there were 4*x yellow balls, which means that there were 7*x green balls.\r \n" ); document.write( "\n" ); document.write( "6 green balls removed. So number of green balls now is 7*x - 6 \n" ); document.write( "3 yellow balls added. So number of yellow balls now is 4*x + 3\r \n" ); document.write( "\n" ); document.write( "After this change, it is given that the number of green balls and yellow balls are equal.\r \n" ); document.write( "\n" ); document.write( "Hence \n" ); document.write( "\n" ); document.write( "Solve for x. Adding 6 to both sides, and subtracting 4*x from both sides,\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Yellow balls = 4*x. Green = 7*x.\r \n" ); document.write( "\n" ); document.write( "Hence number of yellow balls = \n" ); document.write( "\n" ); document.write( ":) \n" ); document.write( " |
