Answer:
There will be 20 grams of fat in 10 pounds of chicken. 
Step-by-step explanation:
Based of the pattern you can tell that the Grams of fat will always be double the amount of pounds. 
2 grams of fat in 1 pound
9 grams in 4.5 pounds
So:
10 * 2 = Grams of fat
10 * 2 = 20 Grams of fat.
So there will be 20 grams of fat in 10 pounds of chicken. 
 
        
             
        
        
        
Answer:
Assuming you mean until the lunch money balance runs out,
$2.20x = $23
Step-by-step explanation:
You spend $2.20 every day.  If you are trying to find how many days until the lunch balance runs out, you need to put in X as your variable.
The last step is to set it equal to $23 dollars to be able to factor out the answer.

The required value of y is 2645 / 77 when x = 77. 
Step-by-step explanation:
1. Let's check the information given to answer:
if y varies inversely as x, and y = 23 when x = 115. Find y when x=77
2. What is y when x = 77?
As the statement "y varies inversely as x" translates into y = k/x
If we let y = 23 and x = 115, the constant of variation becomes
         23 = k ÷ 115
         k = 23 × 115 
         k = 2645 
Thus the specification equation is y = 2645  ÷ x . Now, letting x = 77, we obtain 
           y = 2645 ÷ x 
           y = 2645 ÷ 77 
<u>So, The required value of y = 2645 / 77 when x = 77</u>
