D because of the distribution property
I think u will need to add 5ml acid into the solution to get 25% acid
The Unit Rate is the start of the slope/the y-intercept of the slope.To find that we need to make the slope first.
(shown in the first picture)
We can see that the slope is a linear function/a straight line, and if we just follow the line down the slope we can see that it has a y-intercept/unit rate of 2/3 of 1 whole.

Answer: 
Step-by-step explanation:
You want to isolate s which means get it by itself. So all you gotta do is divide both sides by t
Step-by-step explanation:
v=s^3 s=3^4=81
v=(81)^3
v=531,441 cm^3
