Answer:
25
Step-by-step explanation:
40 * 5/8 = 200/8 = 25
Here the given expression is

We need to find the value of y when x =3 . So we substitute the value of x in the given expression.

So when x=3, y=0.4 and that's the required answer.
Answer: To simplify this problem you combine the like terms in the equation (numbers with the same variables.)
Demo: 12r + -4r = 8r
I believe the range is 25.
