John bought 5 notebooks for a total of $10. Which equation could be used to calculate the cost of the notebooks, y, based on the number
of notebooks purchased, X?

Answer:

-42

Step-by-step explanation:

I put it in a calculator

Answer:

-42

Step-by-step explanation:

the answer should use PEMDAS so it is -42

Answer:

45° + 2k + k = 180°

=> 45 + 3k = 180

=> 3k = 180 – 45

=> k = 135/3

=> k = 45

other two angles :-

2k = 2×45 = 90°

k = 45°

Answer:

The answer is "d" x= r-p / g

Step-by-step explanation:

First let's get rid of the "p" term on the left-side. After you've done that, you have to get rid of the g term. So you divide the x term by the g-term, you do this to both sides.

Answer:

x=10

Step-by-step explanation:

move all terms that don't contain x to the right side and solve.

Second question in Assignment = A) 14

Step-by-step explanation:

x^2 = 14x +49

Answer: 14

Step-by-step explanation:

The first one is 25/4 then 14

Answer:

y = 53

Step-by-step explanation:

To get the answer, first put 19 in place of the x, and then times that iwth two, getting 38, you add that to 15. The answer is 53.

Answer:The Value of the coin after 19 years is $53.

Step-by-step explanation:If x=age, then simply substitute the x in “2x+15” for 19.After you do that you should get y=2(19)+15.Do the math to get y=38+15. Y=53.

Answer:

Step-by-step explanation:

If 6.6 x 10^4 square miles of florida costs $5 X 10^6, then to get one square miles we will follow the given steps below;

6.6 x 10^4 mi² = $5 X 10^6

1mi² = $x

Cross multiply;

$5 X 10^6 * 1 = 6.6 x 10^4 * x

6.6 x 10⁴ x = 5 X 10⁶

Divide both sides by 6.6 x 10⁴  to get x;

6.6 x 10⁴ x /6.6 x 10⁴ = 5 x 10⁶/6.6 x 10⁴

x = 5 x 10⁶ ÷ 6.6 x 10⁴

x = 0.76*10⁶⁻⁴

x = $0.76*10²

Hence the key strokes on a calculator will give the cost the  United States paid for each square mile of Florida is 5 x 10⁶ ÷ 6.6 x 10⁴

Answer:

y = 20x + 12 is the answer

Answer:

The value of 5 is 50,000

Step-by-step explanation:

the answer would be 200 times as large

6x10^5=600000  

3x10^3=3000

600000/3000=200

Answer:

200 times

Step-by-step explanation:

Answer:

A. -8

Step-by-step explanation:

We can look at the table and figure out how we get f(5)

really its just the x value pugged into the x value for the function

after that we look on the table, f(5) is -8 because at the bottum of the table it shows 5 and -8

High Hopes^^

Answer: 2 5/12

Step-by-step explanation:

Answer:

B) It is a product, so it is released by the plant.

Step-by-step explanation:

- Plants release oxygen for humans and humans give carbon dioxide to plants.

- The role of oxygen in photosynthesis is a waste product.

Answer: The oxygen gas is a product, so it is released by the plant.

Explanation:

Photosynthesis is defined as the process by which the producers make glucose with the help of carbon dioxide and water in the presence of sunlight.

The chemical equation representing this reaction follows:

In the above reaction, oxygen gas is written on the product side. So, it is formed by the plant and is released.

Hence, the oxygen gas is a product, so it is released by the plan.

Answer:

f(12) = 11

Step-by-step explanation:

Step 1: Define

f(x) = 2/3x + 3

f(12) is x = 12

Step 2: Substitute and Evaluate

f(12) = 2/3(12) + 3

f(12) = 8 + 3

f(12) = 11

Answer:

(i) Debemos apilar 5 dados para construir el cubo de mayor tamaño.

(ii) Se necesita 121 dados cuadrados para formar el cuadrado con la mayor cantidad de dados posibles, quedando 4 dados sobrantes.

Step-by-step explanation:

(i) Sabemos por la Geometría Euclídea del Espacio que un cubo es un sólido regular con 6 caras cuadradas y longitudes iguales. Cada dado tiene un volumen de 1 dado cúbico y 125 dados dan un volumen total de 125 dados cúbicos.

El volumen de un cubo está dado por la siguiente fórmula:

[tex]V = L^{3}[/tex]

Donde:

[tex]L[/tex] - Longitud de la arista, medida en dados.

[tex]V[/tex] - Volumen del cubo, medido en dados cúbicos.

Ahora, necesitamos despejar la longitud de la arista para calcular la altura máxima posible:

[tex]L = \sqrt[3]{V}[/tex]

Dado que [tex]V = 125\,dados^{3}[/tex], encontramos que la altura del cubo de mayor tamaño sería:

[tex]L =\sqrt[3]{125\,dados^{3}}[/tex]

[tex]L = 5\,dados[/tex]

Debemos apilar 5 dados para construir el cubo de mayor tamaño.

(ii) El área cuadrada formada por cubos está determinada por la siguiente fórmula:

[tex]A = L^{2}[/tex]

Donde:

[tex]L[/tex] - Longitud de arista, medida en dados.

[tex]A[/tex] - Área, medida en dados cuadrados.

Puesto que la longitud de arista se basa en un conjunto discreto, esto es, el número de dados disponibles, debemos encontrar el valor máximo de [tex]L[/tex] tal que no supere 125 y de un área entera. Es decir:

[tex]L \leq 125\,dados[/tex]

Si cada cubo tiene un área de 1 dado cuadrado, entonces un cuadrado conformado por 125 dados tiene un área total de 125 dados cuadrados. Entonces:

[tex]L^{2}< 125\,dados^{2}[/tex]

Esto nos lleva a decir que:

[tex]L < 11.180\,dados[/tex]

Entonces, la longitud máxima del cuadrado con la mayor cantidad de cubos posible es de 11 dados. El número total requerido de cubos es el cuadrado de esa cifra, es decir:

[tex]n = (11\,dados)^{2}[/tex]

[tex]n = 121\,dados[/tex]

Se necesita 121 dados cuadrados para formar el cuadrado con la mayor cantidad de dados posibles, quedando 4 dados sobrantes.

Answer:

x = 2, or x = -1

Step-by-step explanation:

If 2x - 3 is inside the parenthesis (), then the value of x is 2.

If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.

Solution 1

(10x-15) + 4 = 9

10x -11 = 9

10x = 20    -> x = 2

Solution 2 (Not 100% sure)

|10x -15| +4 = 9

10x + 15 +4 = 9

10x + 19 = 9

10x = -10      -> x = -1
