3 1/5 must first converted into 16/5
Then, we can change the division into multiplication by changing 8/20 into it’s reciprocal, 20/8.
This gives us 16/5 * 20/8.
We can then simplify this to 2/1 * 4/1
You then multiply the two fractions to get 8/1 which is equivalent to 8.

Answer:

x=13

Step-by-step explanation:

By the definition of an angle bisector, we have that 8x-23=5x+16.

We can add 23 to both sides to get 8x=5x+39.

We can then subtract 5x from both sides to get 3x=39.

We can finally divide both sides by 3 to get \boxed{x=13}

The answer would be positive 24. The reason being is because of the fact that two negatives when multiplied cancel the negative. Also 12 * 2 is 24 so yeah
