You find the mean by adding each value then dividing the sum by the number of values there were so in this case you'd say 301 + 222 + 287 + 310 + 346 which is 1466 then divide by 5 because there are 5 values and your answer is 293.2!
I hope this helps
        
                    
             
        
        
        
If she went back 5 miles than the displacement would be 0.
Just subtract the amount of miles she went back from the miles she went forward 5 - 5 = 0
        
             
        
        
        
Answer:
-1.5
Step-by-step explanation:
<u>See steps below:</u>
- -8x + 3 - 8x - 3 = 8x+ 27 - 8x - 3          ⇒ add -8x - 3 to both sides in order to collect like terms in the different sides of equation
- -16x = 24                                               ⇒ simplified
- x= 24/-16                                               ⇒ divide
- x= - 1.5                                                   ⇒ answer
