I)
8 - 3x = 23
-3x = 15
x = -5
ii)
5x - 16 = 34
5x = 50
x = 10
iii)
2 - 5x = -3

<u>Answer</u>
The first student was right.
The length of the long side is at least 13 inches.
<u>Explanation</u>
The perimeter of any figure is the distance all round.
Perimeter of a rectangle = 2(l+w). Where l is length and w is the width.
2(l + w) ≥ 30
2{(x-3) + 2} ≥ 30
2(x-3+2) = 30
2(x - 1) ≥ 30
x - 1 ≥ 15
x ≥ 16
When x = 16,
l = 16-3
= 13 inches
The length of the long side is 13 inches. The first student was right.

C=20m+15 represents the relationship between cost and number of months.
Step-by-step explanation:
Given,
Initial fee charged by gym = $15
Per month fee of gym = $20
Let,
m be the number of months.
C be the total cost for m months.
Total cost = Initial fee + Per month fee*number of months
C = 15+20m
C=20m+15
C=20m+15 represents the relationship between cost and number of months.
