Answer:
Step-by-step explanation:
What we know is that A + S = 111. That is, the miles Andre drove plus the miles Scott drove totalled 111 miles. What we also know is that Scott drove quite a bit more than Andre did. Scott drove 7 miles more that ( +7 ) 3 times the number of miles Andrea drove. That looks like this algebraically:
S = 3A + 7
Now we can sub in that value for S to the original equation:
If A + S = 111 and S = 3A + 7, then
A + 3A + 7 = 111 and
4A + 7 = 111 and
4A = 104 so
A = 26 and
S = 3(26) + 7 so
S = 85 miles. 
Scott drove 85 miles.
 
        
                    
             
        
        
        
Answer:
Option A. 
Step-by-step explanation:
step 1
Find the volume of the sphere ( medicine ball) 
The volume is equal to

we have
 ----> the radius is half the diameter
 ----> the radius is half the diameter
Convert inches to feet
Remember that
1 ft=12 in

assume

substitute


step 2
Find the weight of the ball
Multiply the volume in cubic foot by 100

Round to the nearest pound

 
        
             
        
        
        
Yes☺
you are right 7 times 6 is 42 and 7 times. 8 is 56
