There are 5 little lines between 0 and -1, so each line represents 1/5.
 B is located 3 lines to the left of -1, so it would be located at - 1 3/5.
 Am absolute value is a positive number so - 1 3/5 would become 1 3/5.
The answer would be A. 1 3/5

Answer:
B) x = (-3/5)y + 3 
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. 
first, subtract 3y from btoh sides: 
5x + 3y (-3y) = 15 (-3y)
5x = -3y + 15
Next, divide 5 from both sides: 
(5x)/5 = (-3y +15)/5
x = (-3/5)y + 3
B) x = (-3/5)y + 3 is your answer.

First, simplify 

 to 

 / Your problem should look like: 

 = 
 Second,
 Second, multiply both sides by 5. / Your problem should look like: 6 = 2n
Third, divide both sides by 2. / Your problem should look like: 

 = n
Fourth, simplify 

 to 3. / Your problem should look like: 3 = n
Fifth, switch sides. / Your problem should look like: n = 3
Answer: 
n = 3
 
        
             
        
        
        
The volume for 1 a. is 79.50700. (You just multiply 4.3 by itself three times)
I don't know what the second one is though, sorry.
