If two planes intersect there’s alway going to be an intersection point where the two cross over
1) what you would have to do in order to solve this problem is divide 3 3/4 by 10 and the answer is to that will be how much mix is needed in order to make one cup of drink.
work
3 3/4 / 10
answer
375/1000
2) 3 3/4= 10
11 1/4=x
to solve for x (which is the unknown variable) you would have to cross multiply which is doing 11 1/4 multiply 10 which equals 112 1/2 now take this number and divide it by 3 3/4 which gives you an answer of 30 cups with 11 1/4 scoops of drink mix
Answer-
30 cups
x = 27 + 3 √ 129/ 4 , 27 − 3 √ 129/ 4
Note: the entire equation above is divided by 4, not just the last term.
x ≈ 15.26836251, − 1.76836251
That's all I got. Hopefully, this helps. You'll still need to solve for y and z, but its pretty hard :)
