Missing part of the question is;
Find a formula for the number of seats sold if the ticket price is P dollars.
Answer:
(680 - P)/3
Step-by-step explanation:
A) Let x be equal to the number of seats and hence we can conclude that (160 - x) is equal to the number of seats after the increase in price.
Similarly, the increase in ticket price would be equal to (P - 200)
Due to the fact that for every $3 increase, the number of seats decrease by 1, the equation that links the change in the number of seats to the change in ticket price is;
P - 200 = 3(160 - x)
P = 3(160 - x) + 200
Making x the subject;
P = 480 - 3x + 200
P = 680 - 3x
3x = 680 - P
x = (680 - P)/3

Answer:
B *second one down.
Step-by-step explanation:
EF = 1/2(AB + CD)
x+5 = 1/2 (2x + 2 + 2x+4) Combine the like terms on the right.
x+5 = 1/2 (4x + 6) Remove the brackets.
x+5 = 1/2*4x + 1/2*6
x+5 = 2x + 3 Subtract x from both sides
5 = 2x-x + 3
5 = x + 3 Subtract 3 from both sides
5-3 = x
x = 2
EF = x + 5
EF = 2 + 5
EF = 7
The answer is B

Step-by-step explanation:
Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply
