Here's a little known but very useful factoid:

If they're inversely proportional,
then their product is constant.


Here's how to use it:

-- We're told that Y = 8 when X = 7.
So when y=8 and x=7, their product is 56 .

-- If Y REALLY varies inversely as X, then
their product is ALWAYS going to be 56.

-- So when Y=4, X= (56/4) = 14 .

SIMPLE! 30 POINTS AND I WILL GIVE BRAINLIEST
Serhud [2]
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! :)
