You have to divide 25.60 / 20% and that would be 5.12 so to the original answer 25.60 you add 5.12.
Final Answer
30.72
For the first question which is y=x/3, here as we see that both are in top. So they represents direct variation and constant of variation is 1/3 .
For the second question , which is 6/y=x, y is denominator and x is in the denominator. So they represents inverse variation and the constant of proportionality is 6 here .
Answer:theyre the exact same number, so it cant be told
Step-by-step explanation:
I have no idea but I’ll try and solve
Step-by-step explanation:
The equation
is quadratic equation that requires finding discriminant

Since discriminant is negative, this equation has two complex roots. Note that
where
is imaginary unit. Then 
Now the complex roots are
