Algebra.Com's Answer #801277 by greenestamps(13203)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "There are dozens of ways to set this problem up for solving. \n" ); document.write( "I will show you a path to the solution that is a bit unusual but that \"works\" well for me. \n" ); document.write( "You will probably get responses from other tutors that show more traditional algebraic solution methods. \n" ); document.write( "\"In six years Janelle will be three-eighths as old as her mother.\" \n" ); document.write( "With that statement, most ways of setting up the problem would involve working with fractions. I find it easier to avoid fractions, as the computations are a bit easier and faster without them. \n" ); document.write( "So my start on the problem is this: \n" ); document.write( "Let the ages of Mrs. Andrew and her daughter 6 years from now be 8x and 3x. \n" ); document.write( "Then their current ages are 8x-6 and 3x-6. \n" ); document.write( "Mrs. Andrew's age is 2 less than 4 times Janelle's age: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "ANSWERS: \n" ); document.write( "Mrs. Andrew's age is 8x-6 = 40-6 = 34 \n" ); document.write( "Janelle's age is 3x-6 = 9 \n" ); document.write( " \n" ); document.write( " |
