Answer:
D
Step-by-step explanation:
 
        
             
        
        
        
Isolate the variable by dividing each side by factors that dont contain variables
Answer: x=3
 
        
             
        
        
        
C as you know what you’re going through to your point of what time you’re leaving the school you
        
                    
             
        
        
        
X= cost per cherry pie
y= cost per pumpkin pie
NICOLE 
1x + 9y= $60
LISA
11x + 4y= $90
STEP 1 
multiply Nicole's equation by -11 
-11(1x + 9y)= -11($60)
multiply -11 by all terms 
(-11 * x) + (-11 * 9y)= (-11 * 60)
-11x - 99y= -660
STEP 2
add Nicole's new equation from step 1 to Lisa's equation to solve for y (using the elimination method) 
-11x - 99y= -660
11x + 4y= 90
the x terms "cancel out"
-95y= -570
divide both sides by -95
y= $6 per pumpkin pie
STEP 3
substitute y value into either original equation to solve for x
x + 9y= $60
x + 9(6)= 60
x + 54= 60
subtract 54 from both sides
x= $6 per cherry pie
CHECK
11x + 4y= $90
11(6) + 4(6)= 90
66 + 24= 90
90= 90
ANSWER: Each cherry pie costs $6 and each pumpkin pie costs $6.
Hope this helps! :)
        
             
        
        
        
The answer is 8 because you use the order of operations. So it would be 16 divided by 4, then you would do 4+4 which is 8
