Step-by-step explanation:

The given system of linear equations:

x - 2y = 8                        ........ (1)

and 4x + y = 5               ........ (2)

To find, the values of x and y = ?

Multiplying equation (2) by 2, we get

2(4x + y) = 5 × 2  

⇒ 8x + 2y = 10                ........ (3)

Adding equations (1) and (3), we get

x - 2y + (8x + 2y) = 8  + 10  

⇒ x - 2y + 8x + 2y = 8  + 10

⇒ 9x = 18

⇒ x = 2

Put x = 2 in (1), we get

2 - 2y = 8        

⇒ 2y =2 - 8

⇒ 2y = - 6

⇒ y = - 3

∴  x = 2 and y = - 3

The ratios 26:169 and 36 to 78, when expressed as fractions in simplest form, are 2/13 and 6/13, respectively, after identifying and dividing by their greatest common factors.

The task is to express each ratio as a fraction in its simplest form. Let's tackle each ratio one at a time.

A. 26:169

To convert the ratio 26:169 into a fraction in simplest form, we observe that both numbers are divisible by their greatest common factor (GCF), which is 26. Dividing both terms by 26, we get 1/6.5. However, to express this in terms of whole numbers, multiplying numerator and denominator by 2 gives us 2/13, which is the fraction in its simplest form.

B. 36 to 78

For the ratio 36 to 78, first, we convert it into fraction form, which is 36/78. The GCF of 36 and 78 is 6. Dividing both the numerator and the denominator by 6, we get 6/13. Therefore, the simplest form of the ratio 36 to 78 is 6/13.

Answer:

16 ounces

Step-by-step explanation:

The answer is option C. 16 ounces.

The most accurate measurement of 1 pound would be 16 ounces, because, by definition, there are 16 ounces in 1 pound.

Among the options provided:

A. 6 ounces: This is less than 1 pound.

B. 20.099 ounces: This is more than 1 pound.

C. 16 ounces: This is equal to 1 pound.

D. 10 ounces: This is less than 1 pound.

So, the most accurate measurement of 1 pound is 16 ounces.

One pound is most accurately measured as 16 ounces. This is because the imperial system defines one pound as equivalent to 16 ounces.

The question is:

Which is the most accurate measurement of 1 pound? (Remember, there are 16 ounces in a pound.)

A. 6 ounces

B. 20.099 ounces

C. 16 ounces

D. 10 ounces

Answer: yes

Step-by-step explanation:

2(4)=8

Yes, 4 is a solution of 2x = 8

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

For example, 3x – 5 = 16 is an equation.

Given,

4 is solution of 2x = 8,

Then, putting x = 4

2(4) = 8

8 = 8

LHS = RHS

Hence, 4 is a solution of 2x = 8.

If the price is reduced by 40%, it is 100% -40% = 60% of what it was. If 7% tax is added to that, the result is 100% +7% = 107% of the sale price. The final price is ...

Answer:$200 per month is spent.

Step-by-step explanation:

$2400 divided by 12 = $200

The amount of debt remaining as Catherine pays off her $2400 loan over 12 months is expressed by the function D(t) = 2400 - 200t, where t is the time in months.

Catherine is paying off a $2400 loan by making equal payments over a 12-month period until the loan is paid. To express the amount of debt remaining as a function of time in months, let's denote the amount of debt remaining as D(t), where t is the time in months.

Since she is making equal payments over 12 months, the total amount she needs to pay each month is $2400 divided by 12 months, which is $200 per month. Therefore, the function that represents the amount of debt remaining at any time t is given by : D(t) = 2400 - 200t

This linear function shows that for each month that passes, $200 is subtracted from the original loan amount of $2400, representing the payments made towards the loan. Thus, after t months, the amount of debt remaining is calculated by subtracting $200 times the number of months from the initial loan amount.

The volume of the cylinder is [tex]1539 cm^3[/tex]

Step-by-step explanation:

The volume of a cylinder is given by the equation

[tex]V=\pi r^2 h[/tex]

where

[tex]\pi r^2[/tex] is the area of the base, with r being the radius

h is the height

For the cylinder in this problem we know:

h = 10 cm (height)

c = 44 cm (circumference of the base)

The circumference is given by

[tex]c=2\pi r[/tex]

So the radius is

[tex]r=\frac{c}{2\pi}=\frac{44}{2\pi}=7 cm[/tex]

Therefore, the volume of the cylinder is:

[tex]V=\pi (7)^2 (10)=1539 cm^3[/tex]

Answer:

El encuentro se producirá a 240 km de Morelia

Step-by-step explanation:

Velocidades Relativas

Este es un caso donde las velocidades son sumativas, pues ambos móviles van a su encuentro mútuo. La distancia total de 660 km será cubierta por ambos móviles con una velocidad relativa de 70 km/h + 40 km/h = 110 km/h

Ya que :

[tex]\displaystyle v=\frac{x}{t}[/tex]

Tenemos que

[tex]\displaystyle t=\frac{x}{v}[/tex]

[tex]\displaystyle t=\frac{660}{110}= 6 \ h[/tex]

Tomás anda a 70 km/h, así que en 6 horas recorre

[tex]x_t=6\times 70 = 420\ Km[/tex]

Claudia anda a 40 km/h, así que en las mismas 6 horas ha recorrido

[tex]x_c=6\times 40 = 240\ Km[/tex]

Se puede decir entonces, que el encuentro se producirá a 240 km de Morelia

Answer:

       [tex]\large\boxed{\large\boxed{240km}}[/tex]

Explanation:

Since the question is in Spanish, I will give you the answer in Spanish.

En el punto de encuentro las distancias recorridas por Tomás y Claudia suman la distancia que existe entre Ixtapa y Morelia.

La distancia que recorre cada uno es igual al producto de su velocidad por el tiempo de recorrido.

         [tex]distancia=velocidad\times tiempo\\ \\ d_{Tomas}=70km/h\times t[/tex]

          [tex]distancia=velocidad\times tiempo\\ \\ d_{Claudia}=40km/h\times t[/tex]

Los tiempos, [tex]t[/tex] , son los mismos al momento de encuentro, así que puedes crear una ecuación con una sola incógnita:

           [tex]d_{Tomas}+d_{Claudia}=660Km=70km/h\times t+40km/h\times t[/tex]

Puedes obviar las unidades para resolver la ecuación:

         [tex]660=70t+40t\\ \\ 660=110t\\ \\ 660/110=t\\ \\ 6=t\\\\ t=6[/tex]

El resultado es en horas: t = 6 horas.

         [tex]d_{Claudia}=40km/h\times t=40km/h\times6h=240km[/tex]

Y esa es la respuesta. Se encontrarán a 240 km de Morelia.
