Answer:
100 fiddler crabs
Step-by-step explanation:
If the 30 crabs are a representation of the entire population, then 6 marked crabs in a population of 30 would mean that
6 / 30 = 0.20 or 20%
20% of the entire crab population are marked. Since we know that a total of 20 fiddler crabs are marked in the pond then we can divide this number of marked crabs by 20% in decimal form to get the estimated total size of the fiddler crab population
20 / 0.20 = 100 fiddler crabs
Answer:
17
Step-by-step explanation:
Substitute in the points. It doesn't matter if they ar pe variables or not, since the variable b is used already in the equation, making it possible to find.

-3=2b+b
-3=3b
-1=b
b is -1.
Hope this helps!
