The question above makes use of the concept of ratio and proportion in a form of scaling. If we let x and y be the true length and width, the equations that best describe them are,
0.5 cm / 1 inch = 2.5 cm / x in ; x = 5 in
0.5 cm / 1 inch = 4.75 cm / y in ; y = 9.5 in
Therefore, the true length and width of Rueben's flag is 5 in and 9.5 in, respectively.

Answer: Use the second one: 18 - x = 6
the solution for the inequalities 5m - 2 ≤-14 or -2m ≤ -15 is m ≤ - 2.4 or m ≥ 7.5.
First inequality:
5m - 2 ≤ - 14
Add 2 to both the sides:
5 m - 2 + 2 ≤ - 14 + 2
5 m ≤ - 12
Divide both sides by 5:
5 m / 5 ≤ - 12 / 5
m ≤ - 2.4
Other inequality:
-2m ≤ -15
Divide both sides by 2:
-m ≤ -7.5
m ≥ 7.5
So, we get:
m ≤ - 2.4 or m ≥ 7.5
Therefore, we get that, the solution for the inequalities 5m - 2 ≤-14 or -2m ≤ -15 is m ≤ - 2.4 or m ≥ 7.5.
