Answer:
6.0
Step-by-step explanation:
p/sinP = q/sinQ
p/sin(13) = 25/sin(70)
p = sin(13) × 25/sin(70)
p = 5.984697798

Answer:
The cost of a combo meal is $8 and a salad is $4.
Step-by-step explanation:
You have to form simultaneous equations with the given informations. Let combo meal be m and salad is s :
![m + s = 12 - - - (1)](https://tex.z-dn.net/?f=m%20%2B%20s%20%3D%2012%20-%20%20-%20%20-%20%281%29)
![2m + s = 20 - - - (2)](https://tex.z-dn.net/?f=2m%20%2B%20s%20%3D%2020%20-%20%20-%20%20-%20%20%282%29)
Next, you have to solve these equations :
![(2) - (1)](https://tex.z-dn.net/?f=%282%29%20-%20%281%29)
![2m + s - m - s = 20 - 12](https://tex.z-dn.net/?f=2m%20%2B%20s%20-%20m%20-%20s%20%3D%2020%20-%2012)
![m = 8](https://tex.z-dn.net/?f=m%20%3D%208)
![sub \: \: m = 8 \: \: into \: \: (1)](https://tex.z-dn.net/?f=sub%20%20%5C%3A%20%5C%3A%20m%20%3D%208%20%20%5C%3A%20%5C%3A%20into%20%5C%3A%20%20%5C%3A%20%281%29)
![(1)⇒](https://tex.z-dn.net/?f=%281%29%E2%87%92)
![8 + s = 12](https://tex.z-dn.net/?f=8%20%2B%20s%20%3D%2012)
![s = 4](https://tex.z-dn.net/?f=s%20%3D%204)
