Let x = sue
and then let 3x-84 = marcia
therefore
(x)+(3x-84)=132
4x-84=132
4x=216
x=54
however just solving for x doesnt completely solve. it only shows sues money because x = sue
for marcia
3x-84
3(54)-84
162-84
78
therefore Marcia has 78$.
        
             
        
        
        
A) 
Since 5 of the books are new, that means that the other books are used. So, there are 11-5=6. The ratio would be 5:6.
b) 
The ratio is 6:11. You get the 6 from the above problem.
Hope this helps!
        
             
        
        
        
Answer: The cost for the month is $240.
Step-by-step explanation:
Since we have given that 
Cost for the two i.e Aveeno and her boyfriend = $40
They were charged 6 times in a month.
As we know that times stands for multiplication.
So, we need to find the cost for the month, where we multiply 6 with $40 to get the amount for the whole month.
So, the amount for the month would be

Hence, the cost for the month is $240.
 
        
             
        
        
        
Answer:
(2,-2)
Step-by-step explanation:
Point A is 2 units to the right of the origin so the x coordinate is 2
It is also 2 units down so the y coordinate is -2
The point is (x,y) so A = (2,-2)
