Not 100% sure but I think that it is 14.6
9.8 is the middle number which is the median
5*6=30
and 6*5=30
basically we have to take Lcm of 5 and 6=30
30th day they both will be together
1. x=5/2
2. x=3/4-3/4y
y belongs R
Answer: The required system of equations representing the given situation is

Step-by-step explanation: Given that Sam needs to make a long-distance call from a pay phone.
We are to write a system to represent the situation.
Let x represent the number of minutes Sam talked on the phone and y represents the total amount that he paid for the call.
According to the given information,
with prepaid phone card, Sam will be charged $1.00 to connect and $0.50 per minute.
So, the equation representing this situation is

Also, if Sam places a collect call with the operator he will be charged $3.00 to connect and $0.25 per minute.
So, the equation representing this situation is

Thus, the required system of equations representing the given situation is
