Question

Which variable expression represents the word phrase? the sum of 12 and the quotient of 9 and a number

Answer 1

"Sum" tells us it's an addition problem:

One term is 12 and the other is 9/x

SO

The expression is:
12+9/x

Answer 2

The required expression is
`12+(9)/(y)`.

Explanation:

Consider the provided phrase.

The sum of 12 and the quotient of 9 and a number

Let the number is y and the quotient of 9 and a number can be written as:

`(9)/(y)`

Thus, the sum of 12 and the quotient of 9 and a number can be written as:

`12+(9)/(y)`

Hence, the required expression is
`12+(9)/(y)`.
