6n - 10 = 4n + 6
6n - 10 + 10 = 4n + 6 + 10
6n = 4n + 16
6n -4n = 4n - 4n + 16
2n = 16
2n/2 = 16/2
n = 8.
The solution is that the value of n = 8.

Answer:
C. 6.19 mi
Step-by-step explanation:
The angle between the two ship locations as viewed from the lighthouse is ...
23° -14° = 9°
This is opposite the known side of the triangle: 4 miles. The unknown side, the distance to the lighthouse from the second position, is opposite the 14° angle in the triangle. The Law of Sines can be used to find the distance (d) of interest:
d/sin(14°) = (4 mi)/sin(9°)
d = (4 mi)(sin(14°)/sin(9°)) ≈ 6.1859 mi
The ship is 6.19 miles from the lighthouse at the second sighting.
Answer:
0.8
Step-by-step explanation:
The scale factor that takes Q to P
Here, we want to go from Q to P
To get this, we simply divide what we have in P by what we had in Q
Hence, what we do here is;
2/2.5 or 4/5 = 0.8
