Answer:
bro the answer to ur latest question is 27 I think
Given is -
The variables y and x have a proportional relationship, and y = 5 when x = 4.
![\frac{y}{x}=\frac{5}{4}](https://tex.z-dn.net/?f=%5Cfrac%7By%7D%7Bx%7D%3D%5Cfrac%7B5%7D%7B4%7D)
As we have to find the value of x when y= 8 so putting y = 8 in the above relationship, we get :
![\frac{8}{x}=\frac{5}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7Bx%7D%3D%5Cfrac%7B5%7D%7B4%7D)
![5x=32](https://tex.z-dn.net/?f=5x%3D32)
![x=6.4](https://tex.z-dn.net/?f=x%3D6.4)
Hence, the answer is 6.4
