Algebra.Com's Answer #830340 by ikleyn(52794)![]() ![]() You can put this solution on YOUR website! .\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " Usually, even young students of the 4-th grade level can solve such problems using a backward method \r \n" ); document.write( "\n" ); document.write( " and making inverse operations in the inverse order.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \r\n" ); document.write( "Solving this way, you make two steps:\r\n" ); document.write( "\r\n" ); document.write( "\r\n" ); document.write( " (1) You divide 40 and 65 by 5, and you conclude that your numbers are integer numbers between 8 and 13.\r\n" ); document.write( "\r\n" ); document.write( "\r\n" ); document.write( " (2) Then the next and the last step is to subtract 1 from the numbers, obtained in step (1).\r\n" ); document.write( "\r\n" ); document.write( " Doing it, you conclude that your original numbers are integer numbers between 8-1 = 7 and 13-1 = 12.\r\n" ); document.write( "\r\n" ); document.write( "\r\n" ); document.write( "\r\n" ); document.write( "ANSWER. Thus you found out that the original numbers are integer numbers between 7 and 12.\r\n" ); document.write( "\r \n" ); document.write( "\n" ); document.write( "Solved for the 4-th grade level without using equations, with full explanations.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
