Step by Step explanation
We can say that the ratio of males to females is 5:3 and we can solve this:
The total number of parts is 5+3 = 8
520/8 = 65
We can rewrite the ratio as:
5*65:3*65

Correct Answer: Option D
An equilateral triangle is the one having all sides equal in length.
Let each side of the triangle is y units in length.
So, the perimeter of triangle will be = y + y + y = 3y units
This means,
3y = 15x + 30
3y = 3 (5x + 10)
y = 5x + 10
This means, each side of the equilateral triangle is 5x + 10 units in length.
