Question

Write the phrase as an expression. Then evaluate when y = 20

Answer 1

Answer:

$\frac{y}{4}-3$

When $y = 20$, the value of the expression is $2$

Step-by-step explanation:

By definition, when you divide two numbers, the result is known as the "Quotient":

$\frac{a}{b}=c$

 Notice that "c" is the quotient of "a" and "b".

Therefore, the expression for "the quotient of a number $y$ and 4" is:

$\frac{y}{4}$

Now, "3 less than the quotient of a number $y$ and 4" indicates that you must subtract 3 from $\frac{y}{4}$; so you can conclude that the expression is:

$\frac{y}{4}-3$

Substitute $y = 20$ into the expresion:

$\frac{20}{4}-3$

Evaluating, you get that the value of the expression when $y = 20$ is: $=5-3=2$
