Let as consider, we need to find the fixed fee.
Given:
Cost of each ticket = $18
Number of tickets = 5
Total cost = $93
To find:
The fixed fee.
Solution:
Let x be the fixed fee..
Cost of 1 ticket = $18
Cost of 5 ticket = $(5 × 18)
= $90
Total cost 5 tickets = Fixed fee + Cost of 5 tickets



Therefore, the fixed fee is $3.
Question 1:
For this case we must rewrite the following equation:

If we add 3x to both sides of the equation we have:

Thus, we have that an equivalent expression is option C.
Answer:
Option C

Question 2:
For this case we must solve the following equation:

Subtracting 5 from both sides of the equation we have:

Dividing between -5 on both sides of the equation we have:

Answer:
Option B
The first y equals -3 and the second y equals -9
Work: k^2+kf-2f^2
Factor
(K+2f)(k-f)
Answer: (k+2f)(k-f)
Check your work:
K+2f k-f
K^2+2kf-kf-2f^2
K^2+kf-2f^2
The answer is correct
Answer:
B.
Explanation:
B is not a regular polygon because it's not all of the sides and angles are congruent.
