Algebra.Com's Answer #739967 by Theo(13342)![]() ![]() You can put this solution on YOUR website! if x represents joe's age now, then x = 5 * (x - 10) would be the equation that models that.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "you would solve for x in this equation as follows:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "simplify to get x = 5x - 50 \n" ); document.write( "subtract x from both sides of this equation and add 50 to both sides of thsi equation to get 50 = 5x - x \n" ); document.write( "combine like terms to get 50 = 4x \n" ); document.write( "divide both sides of the equation by 4 to get 50/4 = x \n" ); document.write( "solve for x to get x = 50/4 = 12.5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "joe is 12.5 years old today. \n" ); document.write( "10 years ago, joe was 2.5 years old. \n" ); document.write( "12.5 / 2.5 = 5 \n" ); document.write( "today, joe is 5 times as old as he was 10 years ago.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
