Hello!
4/5 = (4 + 8)/x
4x = 5(12) = 60
x = 60/4 = 15
I hope this helps!
The equation can be used to find other combinations of x and y is y^2 = (1/16)x^3
<h3>How to determine the equation?</h3>
The direct variation from the square of y to the cube of x is represented as:
y^2 = kx^3
Where k represents the variation constant.
When x = 4, y = 2.
So, we have:
2^2 = k * 4^3
This gives
4 = 64k
Divide both sides by 64
k = 1/16
Substitute k = 1/16 in y^2 = kx^3
y^2 = (1/16)x^3
Hence, the equation can be used to find other combinations of x and y is y^2 = (1/16)x^3

Well these are supplementary angles so the sum of x and y will be 180. If x is 3/5y then 3/5y+y=180 which equals 112.5.
Answer:
Well just add that number three times and you'll get it
