Question

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

3 less than the quotient of a number y and 4
Expression:
When y = 20, the value of the expression is

Answer 1

`(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":

`(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:

`(y)/(4)`

Now, "3 less than the quotient of a number
`y` and 4" indicates that you must subtract 3 from
`(y)/(4)`; so you can conclude that the expression is:

`(y)/(4)-3`

Substitute
`y = 20` into the expresion:

`(20)/(4)-3`

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