which equation shows y +1/5=3x in standard form A.15x+5y=-1 B.15x-5y=1 C.5x-15y=1 D.15x-5y=-1

The correct equation for Marco to determine the price of each floral arrangement is 'C = 11r + 4', which represents the total cost of the arrangement 'C' calculated by summing the cost of 11 orchids (11 times 'r') and the cost of one vase ($4.00).

To determine the total cost of each floral arrangement that Marco is selling, the cost of the vase and the cost of the orchids used in the arrangement must be added together. As per the question, each arrangement uses one vase that costs $4.00 and 11 orchids. However, the cost of individual orchids is not mentioned and represented by 'r' in the question.

Therefore, the equation Marco should use to find the total cost of each floral arrangement is D. C = 11r + 4. This equation denotes that the total cost of the arrangement 'C' is the sum of the cost of 11 orchids (11 times 'r', where 'r' is the cost of one orchid), and the cost of the vase which is $4.00.

Every odd whole number can indeed be written as the difference of two squares, leveraging the fact that the difference between the squares of consecutive integers is an odd number.

The question whether every odd whole number can be written as the difference of two squares is of arithmetical and algebraic interest. The answer is yes, every odd whole number can be expressed as such. For example, consider the odd whole number 7. This number can be expressed as 4^2 - 3^2, which simplifies to 16 - 9, giving us 7. Generally, for any odd whole number n, we can find whole numbers x and y such that n = x^2 - y^2. This is because we can write n = (m+1)^2 - m^2, where m is an integer. Essentially, m can be taken as (n-1)/2 which ensures that m and m+1 are consecutive integers, hence their squares differ by an odd number, which is n.

The table is:

Number of washes denoted by x: 0, 8, 12

Amount left on card denoted by y: 30, 18, 12

a.       Write an equation that shows the amount of dollars left on the card

Solution:

18 – 30 divided by 8 – 0 = -12/8

On simplest form is -3/2

The equation is y = -3/2x + 30

b.      Explain the meaning of the negative slope above.

As the number of car washes increase, the dollars left on the card decreases.

c.       What is the maximum value of x?

0 = -3/2x + 30

2/3 x 3/2 x = 30/1 x 2/3

Cancel 2/3 x 3/2 and reduce 30 by 3 we get 10, 10 x 2

x = 20

Answer:

At the end of the 5 days week, the number cups of oatmeal left are 59/18.

Step-by-step explanation:

Given that the container has 5 and half or 11/2 cup of oatmeal. Every morning Liam at 4/9 cups of oatmeal and this took place for 5 days. So, multiply it with 5. The total cups of oatmeal for 5 days will be 20/9.

The cups of oatmeal left after 5 days are

(11 / 2) - (20 / 9)

(99 - 40) / 18

59 / 18

So, 59/18 number of cups of oatmeal are left at the end of 5 days.

Step-by-step explanation:

Alex will give each of his friends 7/10 or 0.7 of a pizza when he divides 7 pizzas equally among 10 friends.

Alex has 7 pizzas and wants to share them equally with 10 friends. To find out how much pizza each friend will receive, we can set up a division problem: . This means each person gets 7/10 of a pizza.

Using fractional parts as one method, we can visualize slicing each pizza into 10 equal parts and each friend getting 7 of those slices. Therefore, each person ends up with 7 slices, where each slice is 1/10 of a whole pizza. Hence, every friend gets 7/10 or 0.7 of a pizza when it is divided equally.

Each friend will get 7 tenths of a pizza, or more practically, each friend will receive 0.7 of a pizza.

To solve the problem, we need to divide the total number of pizzas Alex has by the number of friends he wants to share them with.

Alex has 7 pizzas, and he wants to share them equally with 10 friends.

The division of pizzas per friend can be represented by the fraction:

[tex]\[ \text{Pizzas per friend} = \frac{\text{Total pizzas}}{\text{Number of friends}} \][/tex]

[tex]\[ \text{Pizzas per friend} = \frac{7}{10} \][/tex]

[tex]\text{Pizzas per friend} = 0.7[/tex]

The difference in elevation if the lake had formed 149 feet above sea level is 1788 feet.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

We have been given that Oakland has an elevation of 1,639 feet above sea level.

And Lake enriquillo’s elevation is 149 feet below sea level.

We have to determine the difference in elevation if the lake had formed 149 feet above sea level.

So the difference in elevation if the lake had formed 149 feet above sea level as

⇒ 1639 - (-149)

⇒ 1639 + 149

⇒ 1788.

Hence, the difference in elevation if the lake had formed 149 feet above sea level is 1788 feet.

Half of the white squares on a chess board have pieces on them at the start of a game. This is represented by the simplified fraction 1/2.

To calculate what fraction of the white squares on a chess board has chess pieces at the start of the game, you start by considering the total number of white squares. A chess board consists of 64 squares, half of which are white, giving us a total of 32 white squares. At the start, 16 white squares are covered with pieces. Therefore, the fraction of white squares that have chess pieces is 16 out of 32 (16/32).

To simplify this fraction, you look for the greatest common divisor of both the numerator and the denominator. In this case, both 16 and 32 are divisible by 16. After simplifying, 16 divided by 16 gives you 1, and 32 divided by 16 gives you 2, so the simplest form of the fraction is 1/2.

Answer:

the product using the distributive property. (4h+6)(4h-7) is, [tex]16h^2-4h-42[/tex]

Step-by-step explanation:

The distributive property says that:

[tex]a \cdot (b+c) =a\cdot b+ a\cdot c[/tex]

To find the product:

then;

[tex]4h(4h-7)+6(4h-7)[/tex]

Apply the distributive property we have;

[tex]16h^2-28h+24h-42[/tex]

Combine like terms we have;

[tex]16h^2-4h-42[/tex]

therefore, the product using the distributive property. (4h+6)(4h-7) is, [tex]16h^2-4h-42[/tex]
