If [tex]xy = 10[/tex], what is the value of [tex]2 \times \frac{x}{y} \times y^2[/tex]? Please explain your answer.

A. 5
B. 8
C. 10
D. 12
E. 20

x = 10/y,
so 2 × x / y × y 2
= 2 × y 10/ y ​ × y 2
= = 2 × 10 y 2 / y 2
=[tex]=2\times 10
=20[/tex]

e) 20... x/y * y^2 = xy. 2xy = 2*10 = 20

By substituting x = y 10 ​ into the expression 2 × y x ​ × y 2 , we can simplify it to find that it equals 20 . Therefore, the correct answer is option E. 20.
