Answer:
4 + 4 = 8
5 + 5 = 10
Step-by-step explanation:
If we assume Mr Noris restricted himself to integer facts, we require both ...
2n > 6
n < 6
Dividing the first inequality by 2 gives ...
n > 3
Writing the two inequalities as a compound inequality, we have ...
3 < n < 6
There are two integers that satisfy this requirement:
n = 4 or n = 5
So, the doubles fact could have been either of ...
4 + 4 = 8
5 + 5 = 10
