Answer:
x = 6
Step-by-step explanation:
(3x + 20)° are vertical angles with (5x + 8)° meaning that they are the same
3x + 20 = 5x + 8
20 - 8 = 5x - 3x
12 = 2x
2x/2 = 12/2
x = 6

Assuming that you mean
![\sqrt[3]{-\dfrac{27}{125}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-%5Cdfrac%7B27%7D%7B125%7D%7D)
we have
![\sqrt[3]{-\dfrac{27}{125}} = -\dfrac{\sqrt[3]{27}}{\sqrt[3]{125}} = -\dfrac{3}{5}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-%5Cdfrac%7B27%7D%7B125%7D%7D%20%3D%20-%5Cdfrac%7B%5Csqrt%5B3%5D%7B27%7D%7D%7B%5Csqrt%5B3%5D%7B125%7D%7D%20%3D%20-%5Cdfrac%7B3%7D%7B5%7D)
Divide o.946 by 7 that's your awnser.
Im thinking 10 because 10+40=50 and 10x7=70
4.16 10^8
Hope this helps *smiles*
