3x+x=180
x=45 is the right answer
Since, it is not given how many coins did Erica buy at the coin show, so, we can suppose that Erica bought "n" coins from the coin show.
Now, we know that Erica already had 6 coins in her coin collection before she went to the coin show and bought the "n" coins.
Therefore, the total number of coins that Erica will have in her possession after buying "n" coins from the coin show will be 6+n.
Product rule:
Power rule:
The exponential function is its own derivative:
Assuming the base of is , its derivative is
But if you mean a logarithm of arbitrary base , we have
So we end up with
