Answer:
18 miles
Step-by-step explanation:
Let's call it's initial elevation x. Because it descends 3 miles, we now have x - 3. The question says it is now 15 miles above sea level, or x - 3 = 15, and adding 3 to both sides shows that x = 18 miles.
Rotated: The figure can be rotated 2 times. Angle of Rotation: 180 ∘
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 10
950 and 950
Lets just get this done :
10 x 50 = 500
9 x 50 = 450
500 + 450 =
950
---
20 x 50 = 1000
1000 - 50 = 950
Hope this helps!
