Answer:
A
Explanation:
We can get this by simplifying the inequalities
3(x-4) ≤ 18
3x - 12 ≤ 18
3x ≤ 18 + 12
3x ≤ 30
x ≤ 30/3
x ≤ 10
Secondly;
2(x-1) ≥ 6
2x - 2 ≥ 6
2x ≥ 6 + 2
2x ≥ 8
x ≥ 4
So the possible answer that fits both cases is 9
12 won’t work as it is not less than 10; we need an answer that is less than 10 to satisfy the first inequality
