Answer:
R=-12
Step-by-step explanation:
6(1 + 3R) = 2(10R - 9) -4R
Distribute 6 through the parentheses
6+18R=2(10R-9)-4R
Distribute 2 through the parentheses 
6+18R=20R-18-4R
Collect like terms 
6+18R=16R-18
Move the variable to the left-hand side and change its sign
6+18R-16R=-18
Move the constant to the right-hand side and change its sign
18R-16R=-18-6
Collect like terms
2R=-18-6
Calculate the difference
2R=-24
Divide both sides of the equation by 2
R=-12
if you'd make me brainliest that'd be great, if not its ok as well! I hope this helped!!!
 
        
             
        
        
        
Answer:
C is dependent variable 
S is independent variable 
Step-by-step explanation:
Here, give the equation, we are told to identify the independent and the dependent variable 
When we talk of the independent variable, it is that variable which values does not depend on whatever values the second variable in the equation has. It is that variable that is used to find the other variable in the equation 
While the dependent variable depends on the values we input in the equation. It is the variable that we arrive at after plugging different values for the independent variable
now looking at the question, the equation we have is as follows;
c = 0.09s 
To get the value of c which is the cost , we have to input different values of a. As is the amount in sales that we have that will yield the value of the commission to be received 
Thus, we can categorically say that the values of the commission are dependent on the values we get from the sales
Hence, while commission represents the dependent variable, the values of the sales are the independent variables
