An isosceles triangle has two sides of length 9x+3. The perimeter of the triangle is 30x+10. What is the ratio of the perimeter to the base?

Answer 1

The two equal sides total 18x + 6.

That leaves 12x + 4 for the base.

The ratio of perimeter is to base is (30x + 10) / (12x + 4) [It can be reduced]
