Answer:
20 gold coins.
Step-by-step explanation:
Let x represent number of gold coins.
We have been given that each coin weighs one-tenth of an ounce, so weight of x gold coins would be [tex]\frac{1}{10}x[/tex].
We are also told that U.S. Mint sells 2 ounces of American Eagle gold coins to a collector.
We can represent this information in an equation as:
[tex]\frac{1}{10}x=2[/tex]
Multiply both sides by 10:
[tex]10*\frac{1}{10}x=2*10[/tex]
[tex]x=20[/tex]
Therefore, 20 gold coins were sold to the collector.
