15 - 3k = 10(k-5)
Can someone please answer this

Answers

Answer:

k = 5

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

15 - 3k = 10(k - 5)

Step 2: Solve for k

Distribute 10:                              15 - 3k = 10k - 50Add 3k to both sides:                15 = 13k - 50Add 50 to both sides:                65 = 13kDivide 13 on both sides:            5 = kRewrite:                                       k = 5

Step 3: Check

Plug in k into the original equation to verify it's a solution.

Substitute in k:                    15 - 3(5) = 10(5 - 5)Subtract:                              15 - 3(5) = 10(0)Multiply:                               15 - 15 = 0Subtract:                              0 = 0

Here we see that 0 does indeed equal 0.

∴ k = 5 is a solution of the equation.

Answer:

k=5

Step-by-step explanation:

1. Apply distributive property: 15-3k=10k-50

2. Bring all variables to one side: 15-3k=10k-50

+3k +3k

15=13k-50

3. Isolate K by bring the term in it's way to the other side: 15=13k-50

+50. +50

65=13k

4. Isole your variable by divide by 13: 65=13k

65/13 13/13

5=k

If the x- intercept is 2 and the y- intercept is -5 and the slope is 1/3. Write in equation in slope intercept form and standard form.

Answers

Answer:

The equation in slope-intercept form is

[tex]y=\frac{5}{2}x-5[/tex]

The equation in the standard form will be:

[tex]\frac{5}{2}x-y=5[/tex]

Step-by-step explanation:

The x-intercept is obtained when we set the value y=0

As the x-intercept is 2, therefore the point representing

the x-intercept will be: (2, 0)

The y-intercept is obtained when we set the value x=0

As the y-intercept is -5, therefore the point representing

the y-intercept will be: (0, -5)

So we get the two points

(2, 0)

(0, -5)

Finding the slope between (2, 0) and (0, -5)

[tex]\left(x_1,\:y_1\right)=\left(2,\:0\right),\:\left(x_2,\:y_2\right)=\left(0,\:-5\right)[/tex]

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{-5-0}{0-2}[/tex]

[tex]m=\frac{5}{2}[/tex]

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

Here m is the slope

substituting the values m = 5/2 and the point (2, 0)

[tex]y-0=\frac{5}{2}\left(x-2\right)[/tex]

so writing the equation in slope-intercept form

As we know that the slope-intercept form is

[tex]y=mx+b[/tex]

here

m = gradient or slop b = y-intercept

so

[tex]y=\frac{5}{2}\left(x-2\right)[/tex]

[tex]y=\frac{5}{2}x-5[/tex]

Hence, the equation in slope-intercept form is

[tex]y=\frac{5}{2}x-5[/tex]

Writing the equation in the standard form form

As we know that the equation in the standard form is

[tex]Ax+By=C[/tex]

where x and y are variables and A, B and C are constants

As we already know the equation in slope-intercept form

[tex]y=\frac{5}{2}x-5[/tex]

so the equation in the standard form will be:

[tex]\frac{5}{2}x-y=5[/tex]

Dos padres de familia deseaban saber cuáles son los costos de los uniformes escolares que compraron a sus hijos, ya que el primero padre de familia realizó la siguiente compra: 2 pantalones y 2 playeras pagando por ello $820, el segundo padre de familia realizó la siguiente compra, 1 pantalón y 3 playeras pagando por ello $490. Resuelve los siguente cuestionamientos ¿Los padre de familia pagaron al mismo precio cada pantalón y playera? ¿Existe diferencia entre x e y en la ecuación 1 y con respecto a la ecuación 2?

Answers

Answer:

a) ¿Pagaron los padres el mismo precio por cada pantalón y camisa?

Sí, los padres pagaron la misma cantidad por cada pantalón y camisa porque,

1 camisa = $ 40

1 pantalón = $ 370

b) ¿Hay alguna diferencia entre xey en la ecuación 1 y con respecto a la ecuación 2?

Sí, hay una diferencia

Step-by-step explanation:

Dos padres querían saber el costo de los uniformes escolares que compraban para sus hijos, ya que

Representemos pantalones = p

camisas = s

Derivamos las 2 ecuaciones

El primer padre hizo la siguiente compra: 2 pantalones y 2 camisas pagando $ 820 por ella

2p + 2s = 820 ........ Ecuación 1

El segundo padre hizo la siguiente compra, 1 pantalón y 3 camisas pagando $ 490.

p + 3s = 490 ....... Ecuación 2

p = 490 - 3 s

Resolvamos el precio de cada pantalón y camisa.

Nosotros sustituimos

2p + 2s = 820

2 (490 - 3 s) + 2 s = 820

980 - 6s + 2s = 820

980 - 820 = 6 segundos - 2 segundos

160 = 4 s

s = 160/4

s = $ 40

Por lo tanto, el costo de cada camisa = $ 40

El costo de los pantalones =

p = 490 - 3 s

p = 490 - 3 (40)

p = 490 - 120

p = $ 370

El costo de cada pantalón = $ 370

Resuelve las siguientes preguntas.

a) ¿Pagaron los padres el mismo precio por cada pantalón y camisa?

Sí, los padres pagaron la misma cantidad por cada pantalón y camisa porque,

1 camisa = $ 40

1 pantalón = $ 370

b) ¿Hay alguna diferencia entre xey en la ecuación 1 y con respecto a la ecuación 2?

Sí, hay una diferencia

Planteando y resolviendo un sistema de ecuaciones, veremos que cada playera cuesta $40 y cada pantalon cuesta $370.

Definamos:

x = precio de pantalonesy = precio de playeras.

Por la información dada, tenemos que:

2*x + 2*y = $820

1*x + 3*y = $490

Primero respondamos las preguntas:

Notar que ambas preguntas basicamente preguntan la misma cosa:

¿Existe diferencia entre x e y en la ecuación 1 y con respecto a la ecuación 2?

Es realmente imposible saber la respuesta, pero debemos asumir que no, dado que si x e y representan diferentes cosas en cada ecuación, entonces las variables no estan definidas, y el problema es imposible de resolver.

Así que asumimos que los precios son los mismos.

con esto en mente, podemos resolver el sistema:

2*x + 2*y = $820

1*x + 3*y = $490

Primero, aislamos una variable en una ecuación, en este caso voy a aislar x en la segunda:

x = $490 - 3*y

Reemplazamos eso en la primera:

2*($490 - 3*y) + 2*y = $820

$980 - 4*y = $820

$980 - $820 = 4*y

$160/4 = y  = $40

Es decir, el precio de cada playera es $40.

Mientras que:

x = $490 - 3*$40 = $370

Cada pantalon cuesta $370

a small table is 2 feet by 3 feet a large table is twice as long and rwice as wide as the small table. Whats the area of the large in square feet

Answers

Answer:

The area of larger table is 24 square feet.

Step-by-step explanation:

Given are the length and width of small table

[tex]l_s = 2\ ft\\w_s = 3\ ft[/tex]

The area of a rectangular table is calculated by multiplying the length and width. It is also given that the length and width of the larger table is double the length and width of small table

So the length and width of larger table will be:

[tex]l_l = 2*2 = 4\ feet\\w_l = 3*2 = 6\ feet[/tex]

The area of larger table will be:

[tex]A_l = l_l*w_l\\= 4 * 6\\=24\ ft^2[/tex]

Hence,

The area of larger table is 24 square feet.

3) The International Space Station takes 644 minutes to orbit Earth 7 times. About how long does each orbit take? I got 92 am I correct to crazy? 100 minutes 95 minutes 90 minutes 80 minutes

Answers

Given:

The International Space Station takes 644 minutes to orbit Earth 7 times.

To find:

The time taken by each orbit.

Solution:

Total time = 644 minutes

Total number of orbits =7

Now,

[tex]\text{Time taken be each orbit}=\dfrac{\text{Total time}}{\text{Number of orbits}}[/tex]

[tex]\text{Time taken be each orbit}=\dfrac{644}{7}[/tex]

[tex]\text{Time taken be each orbit}=92[/tex]

So, the required time is 92 minutes.

Therefore, you are correct and all options are incorrect.

How would i do this??:: Some kinds of fruit juice are only 10% juice. Other brands are 40% juice how much of each kind of juice should be mixed together to form 5 gallons of punch which is 25% juice?

Answers

Answer:

You should mix

2.5 gallons of the first juice with

2.5 gallons of the second juice

Step-by-step explanation:

Step one

Let the first kind of juice be x

Let the second be y

Given x contain 10% juice

and y contains 40% juice

So for the percentage constituent concentration of each the expression is

0.1x+ 0.4y=0.25(5)

0.1x+0.4y=1.25—----------------1

Step two

Also for the volume of the mixture, we are working with 5 gallons hence the expression

x+y=5-------------------------------2

The system of equation for the situation is

0.1x+0.4y=1.25------1

x+y=5-------------------2

From equation 2

x=5-y

Put x=5-y in the equation

0.1(5-y) +0.4y=1.25------1

0.5-0.1y+0.4y=1.25

0.3y=1.25-0.5

0.3y=0.75

Dividing both sides by 0. 3

y=0.75/0.3

y=2.5

x=5-y

x=5-2.5

x=2.5

The mixture should consist of

2.5 gallons of the first juice with

2.5 gallons of the second juice

Enter your answer in decimal form. Round to the nearest tenth if rounding is necessary.


Enter units as ft., square ft., or cubic ft.

Answers

Answer:

The area of each section of the kennel is 33 square ft

Step-by-step explanation:

The given parameters for the fencing are;

The length of each section, L = 2 ft + The width, 3×W

The total amount of fencing = 113 feet

The The total perimeter of the kennel = 12·W + 7·L = 113

Were we are given L = 2 + 3·W

By substitution, we have;

12 × W + 7 × (2 + 3·W) = 113

33·W + 14 = 113

33·W  = 113 - 14 = 99

W = 99/33 = 3

W = 3 ft.

L = 2 + 3·W = 2 + 3 × 3 = 11

L = 11 ft.

The area of each section of the kennel, A = L × W = 3 × 11 = 33 square ft.

The area of each section of the kennel = 33 square ft.

5.4g + 4 - 1.4g = 1.4g + 20 - 1.4g
then simplify it;
4g+4=20
then, you'll subtract 4 from both sides;
4g + 4 - 4 = 20 - 4
then simplify again;
4g=16
lastly, you will divide 4 from both sides;
4g/4 = 16/4
since 16/4=4, then g=4
