Algebra.Com's Answer #795752 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "You have received, to this point, two formal algebraic solutions. One uses a typical approach and gets to an answer relatively quickly. The other uses a very roundabout approach, eventually reaching an answer. \n" ); document.write( "If a formal algebraic solution method is not required, here is the fastest and easiest way to get the answer. \n" ); document.write( "You are mixing 10-kt and 18-kt gold to get 16-kt gold. \n" ); document.write( "Consider the three numbers on a number line. 16 is 3/4 of the way from 10 to 18. \n" ); document.write( "That means 3/4 of the mixture needs to be the 18-kt gold. \n" ); document.write( "ANSWER: 3/4 of 200g, or 150g, is the 18-kt gold; the other 50g is the 10-kt gold. \n" ); document.write( " \n" ); document.write( " |
