To find the inverse, you need:
1. Switch x and y:

2. Solve again for y:


This the inverse. The reason why there is two "pieces" is because the first one is the inverse for

if

, and the second one is the inverse for

if

.

Answer:
74.2899408284 meters
Step-by-step explanation:
2.7 : 1.69
x : 46.5
46.5/1.69=27.5147928994
27.5147928994*2.7=74.2899408284
9 + 10 + 13 + 13 = $ 45.....combined money (urs and 3 friends)
use a coupon for 8 tokens for $ 1.....u now have $ 44...and 8 tokens
cost of remaining tokens is 4 for $1.....(44 * 4) = 176 tokens
so now there is 176 + 8 = 184 tokens to split 4 ways
184/4 = 46 tokens for each person <==
