Question

Evaluate j/k -0.2k when j =25 and k = 5

Answer 1

When you have an equation that has variables and you know the value of those variables, just plug it it. So plugging the vaules we get

`(25)/(5)-(1)/(5)5`
Just evaluating we get 4

Answer 2

4

Explanation:

To evaluate a function with certain defined values, we must substitute the values ​​in the equation, perform the indicated operations and in this way we obtain the final value.

If j = 25 and k=5

replacing in the equation

`(j)/(k) -0.2k = (25)/(5) -0.2(5)  = 5 -1 = 4`
