(1/2)^-3=1/(1/2)^3=2^3 (by x-n=1/x^n)
(3/5x)^-1=5x/3
Answer:
93.7 miles
Step-by-step explanation:
This problem can be represented as a right angled triangle. The distance between the final point and the starting point is the hypotenuse.
We need to find the hypotenuse. We can use Pythagoras rule:

where opp = opposite side to the angle considered
adj = adjacent side to the angle considered
This implies that:

The car is 93.7 miles far from its starting point.
5n+9=2n
5n+9−2n=2n−2n
3n+9=0
3n+9−9=0−9
3n=−9
3n/3=−9/3
n=−3
