Algebra.Com's Answer #792281 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "Algebraically.... \n" ); document.write( "x = Ryan's age \n" ); document.write( "x+44 = Katie's age \n" ); document.write( "x-6 = Ryan's age 6 years ago \n" ); document.write( "x+44-6 = x+38 = Katie's age 6 years ago \n" ); document.write( "Katie's age 6 years ago was 3 times Ryan's age then: \n" ); document.write( " \n" ); document.write( "Solve using basic algebra; I leave that to you. \n" ); document.write( "Using logical reasoning and some easy mental arithmetic.... \n" ); document.write( "6 years ago, Katie's age was 3 times Ryan's age. Let their ages then be 3x and x; the difference in their ages is 2x. \n" ); document.write( "The difference in their ages is 44 years. So 6 years ago \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "So their ages 6 years ago were x=22 and 3x=66. \n" ); document.write( "So their ages now are 22+6=28 and 66+6=72. \n" ); document.write( " \n" ); document.write( " |
