Answer: the cost of an adult ticket is $9.
The cost of a child's ticket is $13
Step-by-step explanation:
Let x represent the price of one adult ticket.
Let y represent the price of one student ticket.
On the first day of ticket sales, the school sold two adult tickets and three students tickets for a total of $57. It means that
2x + 3y = 57- - - - - - - - - -1
The school took and $70 on the second day by selling two adult tickets and four student tickets. It means that
2x + 4y = 70- - - - - - - - - -2
Subtracting equation 2 from equation 1, it becomes
- y = - 13
y = 13
Substituting y = 13 into equation 1, it becomes
2x + 3 × 13 = 57
2x + 39 = 57
2x = 57 - 39 = 18
x = 18/2
x = 9
Answer:
1/13 and 12/13
Step-by-step explanation:
To answer this question, we need to know the number of cards that are 3 .
Each suite has a single 3 and there are 4 suites.
This means we have 4 cards that are 3
Now, the probability of 3; P(3) would be 4/52 = 1/13
P(of not 3) = 1- probability of 3 = 1-1/13 = 12/13
Answer:
40 miles
Step-by-step explanation:
The time it took to get from one station to the next is 40 minutes.
If the train goes at 60 MPH then it goes 1 mile per minute. (60 minutes in an hour)
If the trip was 40 minutes, and the train goes a mile per minute, the trip would have been 40 miles. (40minutes*1mile)
