Answer:
Step-by-step explanation:
The arithmetic series is
From the given series the general term of the series is
When , we substitute into the general formula to get:
When k=2, we get:
When k=3, we substitute to get:
When k=4, we substitute to get:
When k=5, we get:
For this case we have the following system of equations:
We multiply the first equation by 2:
We have the following equivalent system:
We add the equations:
Equality is not fulfilled. For any value of "x" or "y" the system will have no solution.
Answer:
The system has no solution.

Answer:
JL is 111 miles
Step-by-step explanation:
When we talk of round trips, we mean the distance going plus the distance coming
To get the actual distance between the two places, we need to divide by 2
K to L is round trip 548 miles
K to L distance is 548/2 = 274 miles
K to J round trip is 326 miles
K to J distance is 326/2 = 163 miles
From what we have ;
KL = KJ + JL
274 = 163 + JL
JL = 274-163
JL = 111 miles
To justify our answer, we can see that J is between K and L
if we added the distance KJ and JL, we should get the distance KL
from the calculations we have made, we can see that this is correct and our answer is justified
