Answer:
y = 0.5x
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 1, y = 0.5, then
k = 
= 
= 0.5, hence
y = 0.5x ← equation of variation
Answer:
Change: subtract old value from new value. Example: You had 5 books, but now have 7. The change is: 7−5 = 2. Percentage Change is all about comparing old to new values.

Step-by-step explanation:
Exact form = 1/2
Decimal form = 0.5
Given that a side length is that means its parallel side is also 16. So 16 + 16 is 32 and 72 - 32 is 40 and 40 divided by 2, for two sides of the rectangle youll get 20. With the length being 20 and width being 16, 20 times 16 will get you 320m^2 which is the area.
