Algebra.Com's Answer #81636 by solver91311(24713)![]() ![]() You can put this solution on YOUR website! Your problem statement doesn't say, but I have to assume that the ages of the three people must be expressed in integers, otherwise there is no unique solution.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Since they are ex-teenagers, you know they have to be at least 20 years old. But \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now if you start dividing 26,390 by 20, then 21, and so on, the first number that divides evenly is 26. \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So take the 1015 result and start dividing by 20, 21, etc. again, and you have to get all the way up to 29 before you obtain an even divisor.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So that gives you the three ages, 26, 29, and 35. And the sum is 90 \n" ); document.write( " |
