What do you need help with there is no picture
I’m pretty sure it is angle 8
This is the equation which you can add:
![[c + (3(c + 2))] + [5c]](https://tex.z-dn.net/?f=%5Bc%20%2B%20%283%28c%20%2B%202%29%29%5D%20%2B%20%5B5c%5D)
Simplify:
![[c + 3c + 6] + [5c] = 9c + 6](https://tex.z-dn.net/?f=%5Bc%20%2B%203c%20%2B%206%5D%20%2B%20%5B5c%5D%20%3D%209c%20%2B%206)
And, that's your answer!
Just set up the equation and solve for x, that is the time.
40(0.9-x) = 5x
36 = 45x
x = 36/45
x = 0.8
It took Talia 0.8 hours (48 minutes) to walk home.
