There were 5 adult tickets and 3 student tickets.
Step-by-step explanation:
Step 1:
Assume the number of adult tickets purchased is x and the number of student tickets purchased is y.
From the given data, we can write the following equations;
, take this as equation 1.
Since 8 tickets were purchased,
, take this as equation 2.
Step 2:
We rearrange equation 2 so we can substitute in equation 1.
, take this as equation 3.
By substituting equation 3 in equation 1, we get
Step 3:
Substituting this value of x in any of the previous equations we will get y's value.
Here this value of y is substituted in equation 2.
So we have x = 5 and y = 3. So there were 5 adult tickets and 3 student tickets.
Answer:
5 units
Step-by-step explanation:
Given:-
- The two points C and D are given:
C ( -6 , 5 ) & D ( -3 , 1 )
Find:-
The distance between the two points
Solution:-
- The distance (d) between two arbitrary points ( x1 , y1 ) & ( x2, y2 ) in a cartesian coordinate system is given by the following formula:
Where,
C = ( -6 , 5 ) = ( x1 , y1 )
D = ( -3 , 1 ) = ( x2 , y2 )
- Then we can calculate the distance d between the two given points:
- The distance between the given points C and D is d = 5 units
