Algebra.Com's Answer #170800 by drj(1380)![]() ![]() You can put this solution on YOUR website! Don is twice as old as Irene; Ed is 16 years older than Irene. The sum of all three of their ages is 60 years. Find the age of each person.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 1. Let x be the age of Irene.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 2. Let 2x be the age of Don since he'1 twice as old as Irene.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 3. Let x+16 be the age of Ed since he's 16 years older than Irene.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 4. Then, x+2x+x+16=60 since the sum of their ages is 60.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 5. Solving yields the following steps\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Subtract 16 from both sides of the equation\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Divide by 4 to both sides of the equation\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Step 6. ANSWER: Irene is 11 years old, Don is 22 years old, and Ed is 27 years old.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "I hope the above steps were helpful.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "For FREE Step-By-Step videos in Introduction to Algebra, please visit http://www.FreedomUniversity.TV/courses/IntroAlgebra and for Trigonometry visit http://www.FreedomUniversity.TV/courses/Trigonometry.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "And good luck in your studies!\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Respectfully, \n" ); document.write( "Dr J\r \n" ); document.write( "\n" ); document.write( "http://www.FreedomUniversity.TV \n" ); document.write( " |
