<h3>
Answer: C) n - 10</h3>
============================================
Explanation:
Consider an example of saying "10 less than 50" would mean we compute 50-10 = 40
Another example would be "10 less than 78" so we say 78-10 = 68
In general, we would use algebra to go from "10 less than a number" to "a number - 10" to n - 10
Whatever n is, we subtract 10 from it to get that expression.
From there, we replace n with various numbers. Eg: replace n with 50
n-10 = 50-10 = 40
-----------------
Be careful not to mix up "10 less than a number" with "10 <u>is</u> less than a number". The "is" being the difference. This single word will change what the symbol interpretation will be.
"10 is less than a number" translates to 10 < n
