Question

If 102y = 25, then 10-y equals:(a) -1/5 (b) 1/625 (c) 1/50(d) 1/25(e) 1/5I am sorry the pictures for this problem is not available.

Answer 1

`(995)/(102)`

Step-by-step explanation

First, we have to solve the equation for y. To do this, divide both sides by 102:

`\begin{gathered} (102y)/(102)=(25)/(102) \\ y=(25)/(102) \end{gathered}`

Now, let us find the value of the expression by substituting the value of y into the expression:

`\begin{gathered} 10-y \\ \Rightarrow10-(25)/(102) \\ \Rightarrow(995)/(102) \end{gathered}`

That is the answer.
