Jamie bought a total of 20 pounds of grass seed at the nursery for $168. He paid $9 per pound for Kentucky bluegrass and $6 per pound for Tall Fescue. Which system of equations can be used to find the amount x (in pounds) of Kentucky bluegrass and the amount y (in pounds) of Tall Fescue Jamie purchased?

Determine the number of pounds of Kentucky bluegrass and the number of pounds of Tall Fescue that Jamie purchased from the problem above.

Answer:

Equation 1: 7x + 2y = 12.8

Equation 2: 6x + 3y = 12

Cost of 1 apple: $1.60

Cost of 1 orange: $0.80

Cost of 1 orange: $Step-by-step explanation:

Let's use the elimination method to solve this

Multiply equation 1 by 3

(7x + 2y = 12.8) x 3 = 21x + 6y = 38.4

Multiply equation 2 by -2

(6x + 3y = 12) x -2 = -12x - 6y = -24

The x terms will cancel each other out

21x + 6y = 38.4

-12x - 6y = -24

9x = 14.4

Divide by sides by 9 to isolate the x variable

9x/9 = 14.4/9

x = 1.6

This means an apple costs $1.60

Plug the new x into one of the original equations to find y; we'll use equation 1

7(1.6) + 2y = 12.8

11.2 + 2y = 12.8

Subtract 11.2 from both sides

11.2 + 2y = 12.8

- 11.2        - 11.2

2y = 1.6

Divide both sides by 2

2y/2 = 1.6/2

y = 0.8

This means an orange costs $0.80

SAS

=========================================

Explanation:

SAS = side angle side

One pair of congruent sides is AC = CE (single tickmark). That takes care of one "S" of "SAS".

The other pair of congruent sides is BC = CD (double tickmark). This takes care of the other "S" of "SAS". The order of the "S" terms doesn't matter as long as the angles are between those sides.

The congruent pair of angles is angle ACB = angle ECD. Vertical angles are always congruent. Since we have a pair of congruent angles, this takes care of the "A" of "SAS". The angles are between the sides mentioned in the previous paragraphs.

Answer:

x = 2, y = -1

(x,y) = > (2,-1)

Step-by-step explanation:

2x + 5y = -1

3x + 2y = 4

-3(2x + 5y = -1) = > -6x - 15y = 3

2(3x + 2y = 4) = > 6x + 4y = 8

-6x - 15y = 3

6x + 4y = 8

-11y = 11

/-11  /-11

y = -1

2x + 5y = -1

2x + 5(-1) = -1

2x -5 = -1

   +5   +5

2x = 4

/2   /2

x = 2

(x,y) = > (2,-1)

The first three steps for solving the quadratic equation by completing the square are as follows;

1. [tex]\rm 9x^2 +54x = 7[/tex]

2. [tex]\rm 9(x^2 + 6x) = 7[/tex]

3. [tex]\rm 9(x^2 + 6x + 9) = 7 + 81[/tex]

Given

The quadratic equation given as  9x^2 + 54x = 7.

The highest power of the degree is 2 is known as a quadratic equation.

To solve using the completing the square method.

The first three steps for solving the quadratic equation by completing the square are given below.

1. Write the equation in a way that the constants are on the right side while the terms with x are on the left.

[tex]\rm 9x^2 +54x = 7[/tex]

2. Make sure that the coefficient of the x^2 term is 1.

[tex]\rm 9(x^2 + 6x) = 7[/tex]

3. Adding a term to both sides that will complete the square on the left side.

This is done by dividing the coefficient of the x term by 2 and squaring it.

The same amount should be added to the right side to balance the equation.

[tex]\rm 9(x^2 + 6x + 9) = 7 + 81[/tex]

Answer:

I getting the probability of the adult female that will rent the action movies in DVDs in by dividing the possible probability outcome which is 10% of all adults by the total number of possible outcome. So all of the population of the female is 51% and the ones who rent is only 10%. the probability is 19%

The solution is, 0.20 is the probability that the person rents action-movie DVDs, given that the person is female.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

given that,

Data:

A: the adult is a male, P(A) = 0.49

B: the adult rent action-movie DVDs

C: the adult is a female,  P(C) = 1 - P(A) = 1 - 0.49 = 0.51  

24% of the adults are male and rent action-movie DVDs, then P(A ∩ B) = 0.24

10% of the adults are female and rent action-movie DVDs, then P(C ∩ B) = 0.10

The conditional probability of B (the adult rents action-movie DVDs) given C (the adult is female) is computed as follows:

P(B|C) = P(C ∩ B)/P(C)

          = 0.1/0.51

          = 0.2

Hence, The solution is, 0.20 is the probability that the person rents action-movie DVDs, given that the person is female.

Answer:

Step-by-step explanation:

Function f(g(x)) is the amount of money Raul earns per ticket sold.

here are the steps to find f(g(x)):

Define the functions f(x) and g(x).

f(x) = amount of money Raul earns per ticket

g(x) = number of tickets Raul sells per hour

Substitute g(x) for x in the function f(x).

f(g(x)) = amount of money Raul earns per ticket * number of tickets Raul sells per hour

Simplify the expression.

f(g(x)) = amount of money Raul earns per ticket * number of tickets Raul sells per hour

= amount of money Raul earns per ticket sold

Therefore, f(g(x)) is the amount of money Raul earns per ticket sold.

Here is an example:

Let's say f(x) = $10 and g(x) = 2 tickets/hour. If Raul works for 1 hour, he will sell 2 tickets and earn $20.

f(g(x)) = f(2) = $10 * 2 = $20
