Answer:
3.2t - 2.4
Step-by-step explanation:
Given
- 3.6 - 1.9t + 1.2 + 5.1t ← collect like terms
= (- 1.9t + 5.1t) + (- 3.6 + 1.2)
= 3.2t + (- 2.4)
= 3.2t - 2.4

Step-by-step explanation:
Answer : The value of x and y is 8 and 10 respectively.
Step-by-step explanation :
As we known that if two parallel lines are cut by a transversal line then consecutive interior angles are supplementary.
From the given figure we conclude that:
...........(1)
![5x-y=180-150](https://tex.z-dn.net/?f=5x-y%3D180-150)
............(2)
...........(3)
![5x+y=180-130](https://tex.z-dn.net/?f=5x%2By%3D180-130)
...........(4)
Now we adding equation 2 and 4, we get the value of x.
![5x-y+5x+y=30+50](https://tex.z-dn.net/?f=5x-y%2B5x%2By%3D30%2B50)
![10x=80](https://tex.z-dn.net/?f=10x%3D80)
![x=8](https://tex.z-dn.net/?f=x%3D8)
Now we are putting the value of x in 4, we get the value of y.
![5x+y=50](https://tex.z-dn.net/?f=5x%2By%3D50)
![5(8)+y=50](https://tex.z-dn.net/?f=5%288%29%2By%3D50)
![y=50-40](https://tex.z-dn.net/?f=y%3D50-40)
![y=10](https://tex.z-dn.net/?f=y%3D10)
Therefore, the value of x and y is 8 and 10 respectively.
