ents
b) How many more 18-year
old students than 12-year
old students spent
between 25 and 35 mins

b is the answer that makes most sense

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

i have not got your picture clearly so see it once again
