1. Move the negative sign to the left.
- ![\frac{19}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B8%7D)
*-50
2. Use this rule: ![\frac{a}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D)
![*](https://tex.z-dn.net/?f=%2A)
=![\frac{ac}{bd}](https://tex.z-dn.net/?f=%5Cfrac%7Bac%7D%7Bbd%7D)
-![\frac{19x*-50}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B19x%2A-50%7D%7B8%7D)
3. Simplify - ![\frac{-950x}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B-950x%7D%7B8%7D)
4. Move the negative sign to the left.
-(-950x/8)
5. Simplify 950x/8 to 475x/4
6. Remove parentheses.
The answer is method a and d because they both d the area of the triangle using inverse operations
Answer:
25%
Step-by-step explanation:
120/480=0.25
1. 3!/5! = 3*2 / 5*4*3*2 = 6/120 = 1/20
2. 5! / 8! = 5*4*3*2 / 8*7*6*5*4*3*2 = 120 / 40320 = 1/336
3. 9!/9! = 1
4. 7! / 8! = 7*6*5*4*3*2 / 8*7*6*5*4*3*2 = 5040 / 40320 = 1/8
5. 5! / 7! = 5*4*3*2 / 7*6*5*4*3*2 = 120 / 5040 = 1/42
