i am a number greater than 40.000 and less than 60.000 my ones digit and my tens digit are the same. my ten-thousands digit is 1 less than 3 times the sum of my ones digit and ten digit. my thousands digit is half my hundreds digit, and the sum of those two digits is 9 the ones and tens have to be 4 or 5. ( it need to greater than 40 and less than 60) (3 * (5 + 5)) = 29 so the tenths is 2, or (2 * (4 + 4)) - 1 = 23 same answer 2 the ten-thousanths number is 2 (i believe the teacher meant that the tenths digit not the ten-thousandths hundredths is 4, 6 or 8 we need to take half so it needs to be even thousandths is 2, 3 or 4 so the number is either 44.263
