Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition
x = 2 when y = 2
k = yx = 2 × 2 = 4, hence
y =
← equation of variation
To answer this, first you must know the properties of a square.
With a square, each side is equal in length, which means:
4x- 50 = 60 cm
So now just solve it like a basic equation
Add 50 on both sides
4x - 50 = 60
+50 +50
4x= 110
Now divide both sides by 4
