Algebra.Com's Answer #74403 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! It appears as if you have left something out of this problem. As you wrote it, there are \n" ); document.write( "only three constraints: \n" ); document.write( ". \n" ); document.write( "(1) there are no 1 year olds \n" ); document.write( "(2) the sum of the children's ages is the house number and it is unknown \n" ); document.write( "(3) the product of the children's ages is 90 \n" ); document.write( ". \n" ); document.write( "Here are possible solutions: \n" ); document.write( ". \n" ); document.write( "Solution 1 - Her children are 2, 3, 3 (3-year old twins), and 5. There is no 1-year old, the \n" ); document.write( "sum of their ages is 13 and that is the house number. And the product of 2 times 3 times 3 times 5 \n" ); document.write( "is 90. All constraints are met. \n" ); document.write( ". \n" ); document.write( "Solution 2. Her children are 3, 5, and 6. There is no 1-year old. The sum of their ages is \n" ); document.write( "14 and that is the house number. And the product of 3 times 5 times 6 is 90. All the conditions \n" ); document.write( "are met by this answer also. \n" ); document.write( ". \n" ); document.write( "Solution 3. Her children are 3, 3, and 10 (again 3-yr old twins). There is no 1-yr old. The \n" ); document.write( "sum of their ages is 16 and that is the house number. And the product of 3 times 3 times 10 \n" ); document.write( "is 90. All the conditions are met by this answer also. \n" ); document.write( ". \n" ); document.write( "Solution 4. Her children are 2 and 5 and 9. There is no 1-yr old. The sum of their ages \n" ); document.write( "is 16 and that is the house number. And the product of 2 times 5 times 9 is 90. So this \n" ); document.write( "set of children meets all the conditions for the answer. \n" ); document.write( ". \n" ); document.write( "There are more answer sets that meet the conditions required of the answer. \n" ); document.write( ". \n" ); document.write( "The fact that the kid across the street is older than her oldest has no bearing on the problem. \n" ); document.write( ". \n" ); document.write( "Did you leave something out??? \n" ); document.write( ". \n" ); document.write( " |
