Algebra.Com's Answer #438547 by solver91311(24713) You can put this solution on YOUR website! \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Greater than 400 and less than 600, so the number has to be in the range 401 through 599. Consequently the hundreds digit is either 4 or 5. If it is 4, then the tens digit has to be 5. 4 plus 5 is 9. Then since 12 - 9 = 3, the number has to be 453. But if the hundreds digit is 5, then the tens digit has to be 6. 5 plus 6 is 11, and since 12 - 11 = 1. Then the number has to be 561.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So either 453 or 561 fits the criteria given.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "John \n" ); document.write( " \n" ); document.write( "Egw to Beta kai to Sigma \n" ); document.write( "My calculator said it, I believe it, that settles it \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
