Answer:
93.6 ml
Step-by-step explanation:
12% of that 780 ml is pure acid: 0.12(780 ml) = 93.6 ml
All you need to do is multiply 18*60 = 1080 feet per minute, which is really fast.
Simplifying
-4v + 2v = -12
Combine like terms: -4v + 2v = -2v
-2v = -12
Solving
-2v = -12
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Divide each side by '-2'.
v = 6
Simplifying
v = 6
