Yes this is equal because 3v+v is 4v and if you divide 12v by 3 you also get 4v
Answer:
c is 35

I multiplied both sides, and then simplified the equation.
( plz give me brainliest, that would be most appreciated! )
Just dividing the volumes of the pan, 189 and one bar, 3, suggests that at most she'll be able to cut 63 bars.

9 divides by 1
10.5 divides by 1.5
2 divides by 2.
So no incomplete bars!
