Answer:
(a)x= y+14
(b)x=34, y=20
Step-by-step explanation:
Let the number of tickets sold by your friend = y
Let the number of tickets sold by you=x
You sell 14 more tickets than your friend sells.
Number of tickets sold by you, x= y+14
(a) The system of linear equations that represents this situation is: x= y+14
(b)Together, you and your friend sell a total of 58 tickets.
x+y=54
Since x= y+14
(y+14)+y=54
2y+14=54
Subtract 14 from both sides
2y+14-14=54-14
2y=40
Divide both sides by 2
y=20
Recall, x= y+14
x=20+14=34
You sell 34 tickets and your friend sells 20 tickets.
Answer:

is no more than (it cannot be greater than , but it can be equal to)
x-1/4 ≤
-3/4
x-1/4 ≤-3/4
Answer:
72 inches
Step-by-step explanation:
The area formula is ...
A = LW . . . . . . the product of length and width
The perimeter formula is ...
P = 2(L+W)
You are given the width and the area, so L can be found as ...
128 = L×4
32 = L
Using this in the perimeter formula gives ...
P = 2(32 +4) = 2(36) = 72
The perimeter is 72 inches.
Answer: $362.50.
8.5 x 25 = 212.5,
212.5 + 150.0 = 362.50
Very simple, I hope this helps!
