Answer:
Expression: [tex] \frac{40}{y - 16} [/tex]
When y = 20, the value of the expression is 10.
Step-by-step explanation:
The expression for the phrase "difference of a number, y, and 16" is (y - 16).
Therefore, the quotient of 40 and the "difference of a number, y, and 16" would be written as:
[tex] \frac{40}{y - 16} [/tex]
Let's evaluate the expression when y = 20.
Substitute y = 20 into [tex] \frac{40}{y - 16} [/tex].
Thus:
[tex] \frac{40}{20 - 16} [/tex]
[tex] = \frac{40}{4} = 10 [/tex]
