Answer:
B represents 9. The opposite would be -9
Step-by-step explanation:
D.). I think. yeah because 2 side are equal and 1 isn't.
2p + 7p = 747
9p = 747 divded by 9 = 83
2 * 83 = 166 7 * 83 = 581
Hope it helps
What you want to do is cross multiply so you get 5(x+4)=7(3x+28) then you distrubute the 5 and then you distribute the 5 and the 7 to the number in the parentheses 5x+20=21x+196
subtract 5x on both sides to get 20=16x+196 then you subtract 196 on both sides to get -176=16x last what you want to do is divide 16 on both sides to get x=-11

- Substitute in variables [Tangent]:
![\displaystyle tanx^\circ = \frac{24}{35}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20tanx%5E%5Ccirc%20%3D%20%5Cfrac%7B24%7D%7B35%7D)
- Inverse Trig [Tangent]:
![\displaystyle x^\circ = tan^{-1}(\frac{24}{35})](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x%5E%5Ccirc%20%3D%20tan%5E%7B-1%7D%28%5Cfrac%7B24%7D%7B35%7D%29)
- Evaluate:
![\displaystyle x = 34.439^\circ](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x%20%3D%2034.439%5E%5Ccirc)
- Round:
![\displaystyle x \approx 34^\circ](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x%20%5Capprox%2034%5E%5Ccirc)
