Step-by-step explanation:
Data
A (-5 , -1)
B (-2, 3)
C (6, -3)
Perimeter = ?
Formula
distance AB 
d = 5
Distance BC 
d = 10
Distance AC 
d = 11.2
Perimeter = 5 + 10 + 11.2
= 15 + 
The complete question describes the use of word problems to represent inequalities. The $21 means that there is a limit to the number of stops she can take using the train.
The inequality that represents this scenario is:
From the complete question, we have the following parameters:
Initial Fee = $5
Rate per stop = $2.75
Amount = $21
The inequality that represents the scenario is as follows:
Initial Fee + Rate * Number of stops <= Amount
We use <= because the total charges must not exceed the amount.
Let the number of stops be x.
The above formula becomes

Answer:
∠B = 54 °
Step-by-step explanation:
If sum of two angles add up to 180°, then the two angles are called supplementary.
m∠A + m ∠B = 180°
7x + 7 + 4x - 14 = 180
7x + 4x + 7 - 14 = 180
11x - 7 = 180
11x = 180 + 7
11x = 187
x = 187 ÷ 11
m∠B = 4x - 14
= 4*17 - 14
= 68 - 14
6 + 7b - 7 = 5 + b
7b - 1 = 5 + b
7b = 5 + b + 1
7b = b + 6
7b - b = 6
6b = 6
b = 1
Answer: B)
The answer would be 23w-27x
