Answer:

Step-by-step explanation:

the passengers of  hawaiian airlines  in 2018 were 1.800.000, and for Northwest airlines 192.500.000 (delta)

We replace this number in the equation :

Hawaiian : 0,990 +0.683 x (number of passengers) =

                  0.990 + 0.683 x (1.800.000) =12294012

Northwest airlines: 0,990 +0.683 x (number of passengers) =

                  0.990 + 0.683 x (195.000.000) = 131477501

Suppose Y varies directly with x, and y = 25 when x = 140. what is the value of x when y = 36?
Tema [17]

25y.......140x

36y..........x

Cross multiply

25x= 36*140

25x= 5040

x= 5040/25

x= 1008/5

x= 201.6

When y=36 the x will = 201.6

You have a small business making and delivering box lunches. You calculate your average weekly cost y of producing x lunches usi
kogti [31]

250 lunches are produced by the small business in last week.

<u>Step-by-step explanation:</u>

It is given that,

  • y ⇒ the average cost per week.
  • x ⇒ the number of lunches produced per week.

The function relating these two factors x and y is given as y = 2.1x + 75

  • The cost of the last week is y = $600.
  • The lunches made last week is x = unknown.

<u>To find the value of x :</u>

Substitute y= 600 in the given function,

⇒ 600 = 2.1x + 75

⇒ 2.1x = 600 - 75

⇒ x = 525 / 2.1

⇒ x = 250

Therefore, the lunches prepared last week is 250.

The model below represents an equation. which value of X makes the equation true?<br>​
jeka94

Answer:

The answer to your question is x = 2

Step-by-step explanation:

To solve this problem just count the number of x and the number of numbers ONE on each side of the equation.

- There are three "x"

- There are 4 number one on the left side equation

- There are 10 number one one the right side of the equation

Equation

                   3x + 4 = 10

Solve for x

                   3x = 10 - 4

                   3x = 6

                     x = 6/3

                    x = 2
