Solve the equation 5.4g + 4 = 1.4g +20.
a. Find the value of g.
b. Explain how you can check that the value you found for g is correct. If your check does not work,
does that mean that your result is incorrect? Explain.
a. g=1

Answers

a. g=4
b. first you're going to subtract 1.4g from both sides;
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

Step-by-step explanation:

m∠A=cos⁻¹(35/38) = 22.91954215

round your answer to the nearest tenth.

23 degrees is the measure of the indicated angle in the triangle.

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The given triangle is a right angled triangle.

The side lengths of triangle are 35 and 38.

We have to find the measure of the angle opposite to the right angle.

By using cosine function formula we calculate it.

CosA=Adjacent side/Hypotenuse

CosA=35/38

m∠A=cos⁻¹(35/38)

= 22.91954215

Hence, 23 degrees is the measure of the indicated angle.

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

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

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

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.

We will use the following steps to solve this problem,

Step - (1).

Covert the equations into slope-intercept form.

Step - (2)

If the slopes of the two lines are equal, lines will be parallel.

[tex]m_1=m_2[/tex]

Step - (3)

If the slopes of the two lines are negative reciprocal, lines will be perpendicular.

[tex]m_1\times m_2=-1[/tex]

Line 1: 8x - 6y = -2

          6y = 8x +2

            y = [tex]\frac{4}{3}x+\frac{1}{3}[/tex]

Slope of line 1 = [tex]m_1=\frac{4}{3}[/tex]

Line 2: y = [tex]-\frac{3}{4}x-5[/tex]

Slope of line 2 = [tex]m_2=-\frac{3}{4}[/tex]

Line 3: 4y = -3x + 3

             y = [tex]-\frac{3}{4}x+\frac{3}{4}[/tex]

Slope of line 3 = [tex]m_3=-\frac{3}{4}[/tex]

1). Since, [tex]m_1\times m_2=\frac{4}{3}\times (-\frac{3}{4})=-1[/tex]

   Line 1 and line 2 are perpendicular.

2). Since, [tex]m_1\times m_3=\frac{4}{3}\times (-\frac{3}{4})=-1[/tex]

   Line 1 and line 2 are perpendicular.

3). Since, [tex]m_2=m_3=-\frac{3}{4}[/tex]

   Line 2 and line 3 are parallel.
