An aircraft has a maximum of 30 first class seats and 220 economy seats.
Sidana [21]

Answer:

x\leq 30

y\leq 220

240x+120y

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

x\leq 30

An aircraft has a maximum of 220 economy seats

y\leq 220

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

so

240x+120y

therefore

Three inequalities that represent the situation are

x\leq 30

y\leq 220

240x+120y

Geometry: The rectangle shown has a perimeter of 34cm and the given area. Its length is 5 more than twice it's width. Write and
Thepotemich [5.8K]

w - width

2w + 5 - length

w + w + (2w + 5) + (2w + 5) = 6w + 10 - perimeter

34 cm - perimeter

The equation:

6w + 10 = 34    <em>subtract 10 from both sides</em>

6w = 24    <em>divide both sides by 6</em>

w = 4 cm

2w + 5 = 2(4) + 5 = 8 + 5 = 13 cm

<h3>Answer: Width = 4cm, Length = 13cm</h3>
