The launch site for trigon balloon co. is 250 ft above sea level. a hot air balloon is launched from the site and begins to rise at a rate of 110 ft/min. at the same time, another balloon 2200 ft above sea level begins to descend at a rate of 150 ft/min. a. how long will it be unit the balloons are at the same elevation? b. what will their elevation be then?

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.

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
