Divide:
q + 7
It would be around 138 minutes which is 2 hrs and 18 min so it would be C).
You would need to explain base ten and base 8
X + x+1 + x + 2 = 20
3x + 3 = 20
3x = 17 but can't start with x = 6 because 6+7+8 > 20,
so have start with 5 + 6 + 7 = 18 are the 3 sides.
This is the answer 4828.03
