Unsure of what you're asking.  

If you have an algebraic expression in front of you and see a number there, you could label it as "known" or "a known quantity."  Another word that comes to mind is "constant."

Romashka [77]

Answer:

42%

Step-by-step explanation:

x is for the volume of the  container

the amount filled in the first container=0.30x

the volume of the first container + 50% of the second=(x+x*50%)=1.5 x

the amount of acid in the second container= 1.5x * 50%=0.75x

total amount of acid in the third one =0.3x+0.75x=1.05x

total solution : x+1.5x=2.5x

percentage=1.05x/2.5x= 0.42 or 42%
