Answer:
9 cups
Step-by-step explanation:
We can use ratios to solve
1/3 cup red 4 cups red
----------------- = -------------------
3/4 cup yellow x cups yellow
Using cross products
1/3 *x = 3/4 *4
1/3x = 3
Multiply each side by 3
1/3 x * 3 = 3 * 3
x = 9
The coefficients of x are already opposites, so you can simply add the two equations to eliminate x.
... (-7x +3y) + (7x -2y) = (14) + (-14)
... y = 0 . . . . . . . simplify
... -7x + 3·0 = 14 . . . . substitute the value of x into the first equation
.. x = 14/(-7) = -2
The solution is (x, y) = (-2, 0).

6 is Q1, 2 is minimum, max is 18. Median you just put all numbers in order and find the middle. Q3 is in between those
