2y/5 is the same thing as 2/5 times y so
14=2/5(y) then you divide both sides by y and you get
14/y=2/5 then from there multiply both sides by 1/14 to get
y=0.03
Answer:

Step-by-step explanation:
Triangle DEF is similar to triangle HGF.
Therefore the corresponding sides are proportional.
We can write the following equations for the corresponding sides.
This implies that,

This gives us,

We cross multiply to get,

We divide through by 5 to get,

We multiply to get,

Grouping like terms gives,

We simplify to obtain,
The correct answer is C
Multiply to dun the area of a triangle
C is the correct answer :-)
