I would 100 because the more the trials means the more the results which means you get more of an accurate experiment then if you only did 10. Because since you have so many answers from all of the experiments you can conclude the correct answer from all of the experiments. I hope you get what I’m trying to say
40+90=130
180-130=50
50+130=180
x=130
50+x=180
For this question the answer is x= 5, -1
I hope this solution works
