Question 654537: write the 3 digit number that matches the clues. My number has as many hundred as ones. it has 5 tens. The sum of its digits is 13 Answer by schmidtmomto6(24) (Show Source):
You can put this solution on YOUR website! If you add all three digits you get 13.
The digits are x, and 5 and x (since it says the other 2 digits are the same)
So x + 5 + x = 13.
so 5+2x=13
2x=8, so x=4. So, the answer would be 454.
