Answer:
24
Step-by-step explanation:
Direct variation (with constant of proportionality) has the form:
Where,
- A & B are the 2 variables being compared
is the constant of proportionality
Using cookies, 
, and sugar, 
, we can write:
Substituting 
and 
, and solving for , we have:
Thus, constant of proportionality is 24
No, if you were to have three right angles, the fourth angle would also have to be a right angle. As a result, it would make the shape either a square or a rectangle.
Answer:
x = s, y = t, z = 8 -s -t
Step-by-step explanation:
It can work reasonably well to let s and t represent any of a pair of the variables. In the answer above, we have used x=s, y=t.
You could get more elaborate if you want:
x = 4-s, y = 4-t, z = s+t
