Question

I don't understand this please explain step by step ​

Answer 1

The answer is C.

Explanation:

Think about it as substitution.

The equation given to you is 15n=10.

They are telling you that n is equal to 2/3.

So now, this is where you do the substitution.

1. Substitute 2/3 in for n.

15(2/3)=10

2. Determine if true.

15·2/3=10

3. Are they the same?

10=10

So now you know your answer is C. :)
