ANSWER QUESTION B​

Answer 1

16

Explanation:

We know that: 5 + ? = 10.5

we now need to solve for ? , by using the inverse method

10.5 x 2 = 21

21 - 5 = 16

Now to double check the answer, we substitute the ? with the answer

so, 5 + 16 = 21

21/2 = 10.5 so it is clearly correct

I HOPE THIS HELPED :)
