Question

2 2/5 - - .02 =solve

Answer 1

1

Step-by-step explanation

We want to evaluate the expression given that x = 2/5 and z = -0.2:

`2x-z`

To do this, subsitute the values of x and z into the expression:

`\begin{gathered} 2((2)/(5))-(-0.2) \\ (4)/(5)+0.2 \end{gathered}`

Convert the decimal to a fraction:

`(4)/(5)+(1)/(5)`

Now, simplify:

`\begin{gathered} (4)/(5)+(1)/(5) \\ =(5)/(5) \\ =1 \end{gathered}`

That is the answer.
