Hi Natalie 
We have x/4 = 9
All you have to do is cross multiplication 
x = 4*9
x= 36 
That's all :)
I hope that's help:)
Now if you wanna check my answer just replace x by 36 
36/4 = 9
9= 9 
Because when you divide 36 by 4 you will find 9 
I hope that's help:)

Answer:
Bryce is wrong in step 1 because he did not distribute 3 over 5/3
Explanation
Given the steps taken by bryce as shown, we are to find where he made an error

Given the expression;

Step 1:Expand the bracket using the distributive law;
8/3 = 3c + 3(5/3)
<em>Simplify</em>
8/3 = 3c + 15/3
Step 2: Subtract 15/3 from both sides
8/3 - 15/3 = 3c+15/3-15/3
(8-15)/3 = 3c
-7/3 = 3c
Step 3: Multiply both sides by 1/3
-7/3 * 1/3 = 3c * 1/3
-7/9 = c
Swap
c = -7/9
From the calculation, we can see that Bryce is wrong in step 1 because he did not distribute 3 over 5/3 thereby making his solution incorrect
 
        
             
        
        
        
 Answer:
Egg salad sandwich is proportional to its length
Step-by-step explanation:
Weight of Sandwiches by Length of Roll
                                         6-inch Roll      12-Inch Roll
Cheese sandwich                
                      
Chicken salad sandwich      
                     
Egg salad sandwich             
                   
For cheese sandwich proportion

So, Cheese sandwich weight is not proportional to its length
For Chicken salad sandwich proportion

So, chicken salad sandwich is not proportional to its length
For Egg salad sandwich  proportion

So, egg salad sandwich is proportional to its length
