Answer:
-54
Step-by-step explanation:
8a + 7b + c = 9
We want -6c, but we have c in the equation so multiply by -6
-6(8a + 7b + c) = 9*-6
-48a -42b -6c = -54
Rearranging the equation
-6c - 48a - 42b = -54
 
        
                    
             
        
        
        
<u>What we know</u>:
- Bird feeder capacity:             -->  2 4/5 cups
- Samantha's scoop capacity: -->  7/10 cups
<em>Lets first convert the mixed partial fraction --> improper fraction</em>
<em>        --> for easier calculation</em>
<em />
<u>After Conversion:</u>
- Bird feeder capacity:             -->  14/5 cups
- Samantha's scoop capacity: -->  7/10 cups
<u>To find how many scoops of birdseed will Samantha put into the feeder we must:</u>
   --> divide the total capacity by the scoop's capacity
        --> find the number of scoops:
<u>Solve:</u>
   
Thus the total number of scoops that Samantha will put into the bird feeder is <u>4</u>
<u></u>
<u>Answer: 4</u>

Hope that helps!
