1.) 8.88= 4.44 (x -7)
 8.88 = 4.44x - 31.08
 +31.08 +31.08 
 39.96 = 4.44x 
 39.96 / 4.44x 
 9 = x
        
                    
             
        
        
        
Answer: 17.75 pounds
Step-by-step explanation:
After putting soil in the first flower bed, Layla's bag was ⅝ full. The pound of soil will be: = 5/8 × 10 = 6.25 pounds 
Eliana's bag was ⅖ full. The pound of soil will be: = 2/5 × 10 = 4 pounds
Nature's bag was ¾ full. The pound of soil will be: = 3/4 × 10 = 30/4 = 7.5 pounds
The number of pounds of soil that they put in the first flower bed altogether will be:
= 6.25 + 4 + 7.5
= 17.75 pounds 
 
        
             
        
        
        

Given that : g(x) = 4x + 4 .
So , in order to find the value of g(4) , just substitute x = 4 in the given function . 
Here , 
=> g(x) = 4x + 4 .
=> g(4) = 4 × 4 + 4 .
=> g(4) = 16 + 4 .
=> g(4) = 20 .
