Answer:
x + y = 220
25 x + 15 y = 4650
The above system can be used to find the number of adult and student tickets sold.
Step-by-step explanation:
Let us assume the number of Adult's ticket sold = x
And The number of student's tickets sold = y
Now, total number of tickets sold = 220
⇒ x + y = 220
Cost of 1 adult Ticket = $ 25
⇒ Cost of x adult tickets = x ( $25) = 25 x
Cost of 1 student Ticket = $ 15
⇒ Cost of y student tickets = y ( $15) = 15 x
Also, the total amount made from selling all tickets = $4650
⇒ 25 x + 15 y = $4650
Here, the given system of equations are:
x + y = 220
and 25 x + 15 y = 4650
The above system can be used to find the number of adult and student tickets sold.
Answer:
x=2
Step-by-step explanation:
6x+2x-9=7
Combine like terms on each side of the equation
8x-9=7
Add 9 to each side
8x=16
Divide by 8 on each side
x=2
Answer: -2
Step-by-step explanation:
For the answer to the question above, since the triangle is isosceles, the two legs have equal length. The coordinates of two vertices are given
P(3,3)
Q(3,1)
Assuming that PQ and QR are the legs of equal length, the distance between Q and R must be the same as the distance between P and Q
d = √[(3-3)² + (3-1)²
d = 2
Therefore, the coordinates of P is
(5,1)
