Step-by-step explanation:

From the original question, we can rewrite this as:

An airplane company is determining the difference in selling price if rows of first-class seats are added to a new design. The total selling price for one new row is f(r) = 4,000r. Each row in first class eliminates a pair of rows of economy seats. The total price for each pair of removed rows is e(r) = 1,800r. Which is d(r), the profit or loss for adding r rows of first class seats?

f(r) = 4000r

e(r) = 1800r

d(r) = ? (profit or loss)

Assuming we had added a row of first class seats,

+ f(r) = 4000r

But we had to remove a pair or rows from the economy seats,

- e(r) = 1800r

Translating these into one equation:

d(r) = f(r) - e(r) = 4000r - 1800r = 2200r

Therefore, OPTION A.) d(r) = 2200r

The value of d(r) will be 2200r. The correct option is A.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Answer and explanation:

If Magdala is trying to divide 2.12 by 4 then she would definitely need to change the place value of the dividend(2.12) and the divisor(4). In other words, both numbers need to be whole numbers.

To make 2.12 a whole number, we shift the decimal point two places to the right of the decimal point to get 212. We do same for 4 to get 400, since both numbers have to have their place values adjusted equally.

We divide 212 by 400 to get 0.53

Therefore 2.12 divided by 4= 0.53

There are 30 two-point questions and 20 five-point questions.

What is equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

According to questions, Brandon took a 50-question exam worth a total of 160 points.

There were x two-point questions and y five-point questions.

So,[tex]y=50-x[/tex]

Now, according to question, we will get the following equations

[tex]2x+5(50-x)=160[/tex]

⇒[tex]2x+250-5x=160[/tex]

⇒[tex]-3x=-90[/tex]

⇒[tex]x=30[/tex]

[tex]y=50-30\\[/tex]

Answer:

x = 3

y = 2

Step-by-step explanation:

5x - 3 = 6y

5x + 3 = 9y

y = 5/6 x - 1/2

5x + 3 = 15/2 x - 9/2

-5/2 x + 15/2 = 0

-5/2 (x - 3) = 0

x = 3

Answer:

x = 3

y = 2

Step-by-step explanation:

because it's a rectangle, opposite sides are equal

AD = BC

AB = DC

so we can use their measures to create a system of equations:

5x + 3 = 9y

5x - 3 = 6y

if we multiply the first equation by -1 we can eliminate the x-values:

-(5x + 3 = 9y)

 -5x - 3 = -9y

+ 5x - 3 = 6y

        -6 = -3y

         y = 2

If y = 2 then BC = 12 and we can set up this equation:

12 = 5x - 3

15 = 5x

3 = x
