SOLUTION:
To begin with, let's establish the problem as the following:
5 + 7
An effective method to solve this problem would be to convert it into a visual representation in order to obtain a better understanding.
As attached in the diagram above, I have demonstrated the problem visually. The five red circles / dots represent the five in the problem whilst the 7 circles / dots represent the 7 in the problem. Now we must simply count each of the circles / dots to obtain the total number which would be our final answer.
We can also simply use our fingers on our hands to solve the problem by counting 5 on our fingers and then adding 7 or vice versa to obtain the final answer.
FINAL ANSWER:
Hence, through either of these two methods, we obtain the final answer to the problem as follows:
5 + 7 = 12
Hope this helps! :)

Answer:
The radius of the inner circle is 14 ft. Since the outer circle is 3 ft more than the inner circle, its radius is 17 ft. The circumference formula is 2(pi)radius (or 2(22/7)17 in this case). The circumference of the outer circle is 106.85 ft (or 106.9 if rounding). To find the difference, you would subtract the smallest FROM the greatest:
106.85 - 88 = 18.85 ft (or 18.9 if rounding)
12 is a
13 is b
14 is d
15 is 1 217/1250
