The first three are dependent variables as the outcomes could potentially change due to any of these circumstances.
The last one is an independent variable due to the fact that rolling a die several times will not affect the next outcome.

Answer:
a.V=5/6T
b. 350 ml
Step-by-step explanation:
a.
V∝T
or V=kT
where k is a constant.
V=250 ml
T=300° K
250=300 k
k=250/300=5/6
so V=5/6 T
b.
V=5/6 T
=5/6×420
=5×70
=350 ml
Add 3 and 12 , cancel -2 y+2y and and add 14 and 14
3x-2y=14
12x+2y=14
15x=28
Divide both sides by 15
X=28/15
3x 28/15 -2y=14
Y=-21/5
(X,y)=28/15, -21/5
3x 28/15 -2x(-21/5)=12x 28/15 +2x(-21/5)=14
14=14=14
(x, y)=(28/15, -21/5) is the answer
