Question

Evaluate each expression for the given value 2/ 5 - 3 1 /2 for k = 15

Answer 1

The value of expression for k = 15 is
`(13)/(5)`

Explanation:

Given expression as :

`(2)/(5)` k - 3
`(2)/(5)`

Or,
`(2)/(5)` k - 3 -
`(2)/(5)`

Or,
`(2)/(5)` k -
`(17)/(5)`

Now, for k = 15

The expression is

`(2)/(5)` × 15 -
`(17)/(5)`

Or,
`(30)/(5)` -
`(17)/(5)`

Or, 6 -
`(17)/(5)`

Or,
`(30-17)/(5)`

So,
`(13)/(5)`

Hence The value of expression for k = 15 is
`(13)/(5)` Answer
