X-18 = 2 (X-25)
x-18 = 2x - 50
-18 = x - 50
32 = x
check
32-18 = 14 = 2(32-25) = 2*7
32 is the answer
Answer:

Answer:
a)5/x+1/4=6
Step-by-step explanation:
We need to find the circumference of the orbit of the spacecraft. Let's first determine the radius of the orbit. From the planet's center, the spacecraft is 3,390 + 365 km away = 3,755 km.
Circumference = 2πr
C=2(π)(3755 km)
C≈ 23593 km
