Answer 2

Answer:
`4`

Explanation:

For this exercise it is important to remember the multiplication of signs:

`(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-`

Given the following expression provided in the exercise:

`(j)/(k) -0.2k`

You need to follow the steps below in order to find its value when
`j=25` and
`k=5` :

Step 1: You must ubstitute
`j=25` and
`k=5` into the expression:

`=(25)/(5) -0.2(5)`

Step 2: Now you can solve the multiplication:

`=(25)/(5) -1`

Step 3: You must divide the numerator 25 by the denominator 5. Then:

`=5-1`

Step 4: Finally, you must solve the subtraction. Therefore, you get:

`=4`
