Answer:
C. More than 1 solution
Step-by-step explanation:
Divide the second equation by 3.
y -x = -3
Add x.
y = x -3
This matches the first equation exactly, meaning that any solution to the first equation is also a solution to the second equation. There are an infinite number of possibilities. There is "More than 1 solution."
Hello!
First you have to add the number of fish
52 + 61 + 87 = 200
Then you find the percentage of grass carps
61/200 = 0.305
Then you multiply what you just got with the estimated sample
800 * 0.305 = 244
The answer is 244
Hope this helps!
