Determine the average distance
<em>This question has missing details, as the distance he hits the ball in each tryout is not given. However, I'll give a general explanation.</em>
<em></em>
The mean is calculated as:

 means the sum of the distance in each tryout.
 means the sum of the distance in each tryout.
Assume that the distance in the 10 tryouts are: 
So, the mean is:



<em>So, the average distance is 6.5</em>
 
        
                    
             
        
        
        
Answer:
6(3+2)
Step-by-step explanation:
Distributive property:
ab + ac = a(b+c)
where a = greatest common factor (GCF)
GCF of each factor 
18 = 2×3×3
12 = 2×2×3
GCF of 18 and 12 = 2×3
= 6
Therefore,
18 + 12 = 6(3) + 6(2)
= 6(3+2)
Where,
6 = a
3 = b 
2 = c
ab + ac = a(b+c)
 
        
             
        
        
        
Answer:
Step-by-step explanation:
If Elena walk 12 miles, and then 0.25 that distance
0.25=1/4
12*1/4=3 miles is 1/4 of the distance
she walked in total 12+3=15 miles
choice A =12+12*1/4

Answer:
x=(y+9)/(1+2w)
Step-by-step explanation:
x-9+2wx=y
We make x the subject
x+2wx=y+9
x(1+2w)=y+9
Divide both sides by (1+2w)
x(1+2w)/(1+2w)=y+9(1+2w)
x=(y+9)/(1+2w)
