Question

What is the value of the expression if z=27 7/9z-18+1/3z

Answer 1

The answer for this question would be: 4/81.

Answer 2

The value of the expression is 12.

Explanation:

Given : Expression
`(7)/(9)z-18+(1)/(3)z` , where z=27

To find : The value of expression when z=27

Solution :

Given expression:

`(7)/(9)z-18+(1)/(3)z`

Substitute value of z=27

`=(7)/(9)(27)-18+(1)/(3)(27)`

`=7* 3-18+1* 9`

`=21-18+9`

`=21-9`

`=12`

Therefore, The value of the expression is 12.
