What is the value of x?
lina2011 [118]

Answer : The value of x is 5.

Step-by-step explanation :

According to the angle bisector theorem, an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.

That means,

\frac{AB}{BD}=\frac{AC}{CD}

\frac{9}{2x-1}=\frac{15}{3x}

By the cross multiplication, we get:

9\times 3x=(2x-1)\times 15

27x=30x-15

30x-27x=15

3x=15

x=\frac{15}{3}

x=5

Therefore, the value of x is 5.

How do I change a decimal in to a fraction .333
stepan [7]
Well, with recurring numbers, like .333333..., instead of the fraction being /100, it's actually out of 99 surprisingly. 

So in that case, it turns into 33/99

If it were 0.6667,
it would be

66/99
