Algebra.Com's Answer #107419 by Monarch(4) ![]() You can put this solution on YOUR website! Lets suppose X is the 3rd number.\r \n" ); document.write( "\n" ); document.write( "so average V = (X+Y+Z)/3\r \n" ); document.write( "\n" ); document.write( " 3V = X + Y + Z \n" ); document.write( " X = 3V - Y - Z \n" ); document.write( "So the answer is D. 3V - Z - Y \n" ); document.write( " |
