Answer:



Step-by-step explanation:
Let
x ----> the number of first class seats
y ----> the number of economy class seats
we know that
An aircraft has a maximum of 30 first class seats
so

An aircraft has a maximum of 220 economy seats

A flight will be cancelled if the money taken for the seats is less than $28,800.
so

therefore
Three inequalities that represent the situation are



Answer:
13/4 or 3 1/4
Step-by-step explanation:
5 3/8 = 43/8
2 1/8 = 17/8
43/8 - 17/8 = 26/8
26/8 = 13/4
18x^3 +9x / 6x^2 = 3x
18x^3
--------
0 9x
so than (18x^3 +9x) divided by 6x^2 will be equal 3x and the remainder is 9x
In 1 meter there are 1,000 millimeter.
When you go from small (mm) to big (m) you always divide the small (mm) by what the equivalent of 1 big (m) but in terms of the small (mm)
^^^That's a bit confusing so I will work it out so it makes more sense...

^ this is the equivalent to 1 meter (the big in this case)
3 m = 3,000 mm
Hope this helped! Let me know if there is anything else that I can do!
