Answer:
-15 meters
Step-by-step explanation:
The tunnel of fear starts at 0 meters, goes up to 50 meters, then drops 65 meters. This expressed as an equation is:
(0+50)-65=x
50-65=x
-15=x
it is a cycle or series of cycles of economic expansion and contraction
Value of x is 1
⇒ 2x + 4 = 7x - 1
⇒ -5x = -5
⇒ x = 1
