Answer:
The number of red circles to be added would be equal to 8 times the original amount of red circles
Step-by-step explanation:
Let
x ----> the number of red circles
y ----> the number of blue circles
Originally
----> equation A
How many more circles would need to be added to make the ratio of red to blue 3:1
Let
n ----> the number of additional red circles
----> equation B
substitute equation A in equation B
solve for n
therefore
The number of red circles to be added would be equal to 8 times the original amount of red circles

Answer:
Omg I need help on that too
Step-by-step explanation:
I'm not totally sure what you are asking, but maybe this is a question about dependent and independent variables?
If so, these types of variables are used in math and science as measures. In math, independent variables and dependent variables are the "tools" used in an experiment.
Independent variables are the variables that are controlled during the experiment. These variables do not change during the experiment.
Dependent variables are the variables whose values change based on the independent variables. These variables are the "outcome" portion.
I have no idea if this answers your question or not. All I can say is that the "controlled" part of a sample would be the independent variable.
