At a school assembly four out of the first 10 students were wearing spirit wear. Based on this information, if 500 students were at the assembly, then how many students could be expected to be wearing spirit wear?

200

Step-by-step explanation:

200 I believe

Step-by-step explanation:

I made four out of ten a fraction 4/10 then I multiplied 10 by 50 and 4 by 50 and got 200/50 so it would be simplified. I'm sorry if it doesn't make sense

is only a line? i think so

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.
