Y is 2.25 when x is 9.

The relationship between two values where their ratio equals a constant number is known as a direct proportion or direct variation. It is symbolized by the proportional sign (). According to the direct proportion formula, if y is directly proportional to x, we can state that y = kx, where k is a constant. The generic form of the direct proportion equation is also y = kx. where k is the proportionality constant.

Given Data

If x and y vary directly and y is 24 when x is 6, find y when x is 9.​

It is direct proportional

So,

y = kx

To find constant,

k = [tex]\frac{y}{x}[/tex]

x = 6 and y = 24

k = [tex]\frac{6}{24}[/tex]

k = [tex]\frac{1}{4}[/tex]

When x = 9,

k = [tex]\frac{1}{4}[/tex]

y = kx

y = [tex]\frac{1}{4}[/tex](9)

y = [tex]\frac{9}{4}[/tex]

y = 2.25

Y is 2.25 when x is 9.

The operation of Subtraction can be used to result in the smallest co-efficient term on the x term.

In the given question, Two functions are given f(x) = 3x - 1, and g(x) = 3x + 4. Now we have to find out which mathematical operation results in the smallest co-efficient term on x. We know that the basic Operations are:    

=> Now, we use the operation of Subtraction for the two functions. Which can be calculated by: f(x) - g(x), Calculating we get:

=> (3x - 1) - (3x - 4)

=> 3x -1 -3x + 4

What is Fraction?

A fraction, which also symbolizes a piece of a whole, is a mathematical symbol for any number of equal parts. When expressed in common English, a fraction, such as 1/2, 8/5, or 3/4, represents the number of components of a specific size.

The value of m must be determined.

As can be seen in light of the query

The formula is m/4 = 26 / 13

The equation will now be solved for m m/4 = 26 / 13

The result of multiplying 4 on both sides is

(m/4) x 4 = (26/13) x 4

m = (26 x 4)/13

m = 104/13.

Answer:

32

Step-by-step explanation:

this expression cannot be simplified because there are no like terms to combine with the numbers in the expression.

the number that goes in the ? is 32

The number of children and the number of adults that swam in the swimming pool that day are 69 and 366 respectively.

Given that:-

Total number of people that swam in the swimming pool = 435

Price for children = 1.25

Price for adults = 2

Total receipts = 818.25

We have to find the number of  children and the number of adults that swam in the swimming pool that day.

Let the number of children that swam that day be x and,

the number of adults that swam that day be y.

Hence, we can write,

1.25x + 2y = 818.25  ...(1)

x + y = 435 ... (2)

Solving the linear equation in two variable by elimination method

Multiplying (2) by 2 , we get

2x + 2y = 870 ... (3)

(3) - (1)

0.75x = 870 - 818.25

0.75x = 51.75

x = 51.75/0.75

x = 69

From (2), we can write,

69 + y = 435

y = 435 - 69

y= 366

Hence, the number of children and the number of adults that swam that day are 69 and 366 respectively.

The amount of rye seed and bluegrass seed used in the mixture is 109.8 and 70.2 pounds respective.

In response to the given question;

Let's say the amount of rye seed is 'x.'

The cost of rye seed = $6.50 per pound

Let's say the amount of bluegrass seed is 'y.'

The cost of bluegrass seed = $3.50 per pound.

The total seeds are 180 pounds.

Thus,

x + y = 180

x = 180 - y .......eq 1.

The other equation for the total cost of $5.33 per pound is;

6.50x + 3.50y = 5.33×180

Put the value of x from eq 1.

6.50(180 - y) + 3.50y = 959.4

1170 - 6.50y + 3.50y = 959.4

3y = 210.6

y = 70.2

x = 180 - 70.2 = 109.8

Thus, the amount of rye seed and bluegrass seed used in the mixture is 109.8 and 70.2 pounds respectively.
