Algebra.Com's Answer #200785 by dabanfield(803) ![]() You can put this solution on YOUR website! To make sure the smallest integer is greater than 0 let x+2 be the smallest integer. Then the next four consecutive even integres are x+4, x+6, x+8 and x+10.\r \n" ); document.write( "\n" ); document.write( "We are given that:\r \n" ); document.write( "\n" ); document.write( "(x+10)/(x+2) = 2\r \n" ); document.write( "\n" ); document.write( "So:\r \n" ); document.write( "\n" ); document.write( "x+10 = 2*(x+2) \n" ); document.write( "x+10 = 2x + 4 \n" ); document.write( "x = 6\r \n" ); document.write( "\n" ); document.write( "The middle integer is x+6 = 12.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
