El lado de cada portavasos de yute, cuya área superficial es de 64 centímetros, mide 8 centímetros.

Tras una lectura al enunciado de esta pregunta se infiere que que Lorena compró portavasos de yute , cuya área superficial es de 64 centímetros de forma <em>cuadrada</em>, puesto que la ecuación de área de un cuadrado es en función exclusivamente de la longitud del lado.

En consecuencia, tenemos que la medida del lado del portavasos está determinado por la siguiente ecuación de área superficial:

$l = \sqrt{A}$ (1)

Donde:

$l$ - Lado, en centímetros.
$A$ - Área, en centímetros cuadrados.

Si sabemos que $A = 64\,cm^{2}$ , entonces la medida del lado del portavasos de yute es:

$l = \sqrt{64\,cm^{2}}$

$l = 8\,cm$

El lado de cada portavasos de yute, cuya área superficial es de 64 centímetros, mide 8 centímetros.

I need help with this pls be nice and tell me the answer :)

Answer:

m=-10

Step-by-step explanation:

just to make this easier ill subtract 2 from each side to get

2/3m = 1/6m -5

now multiply each side by 6 to get rid of denominators (this just makes it easier)

now in the next steps we simplify

4m = 1m -30

3m= -30

m=-10

Answer:

(x, y, z) = (1, -3, 1)

Step-by-step explanation:

Any number of calculators and/or web sites can be used to solve this system of equations. It can be helpful to familiarize yourself with your graphing calculator's capabilities in this area. The solution from one such site is shown below:

(x, y, z) = (1, -3, 1)

Both y and z show up in these equations with coefficients that have a magnitude of 1. This means you can easily use one of those equations to create a substitution for y or for z.

Using the first equation to write an expression for z, we have ...

z = 4x +3y +6

Substituting that into the second and third equations gives ...

6x -y +3(4x +3y +6) = 12 ⇒ 18x +8y = -6

8x +2y +4(4x +3y +6) = 6 ⇒ 24x +14y = -18

Now, we can subtract 4 times the first equation from 3 times the second to eliminate x:

3(24x +14y) -4(18x +8y) = 3(-18) -4(-6)

10y = -30

y = -3

Substituting into the first equation (of the equations in x and y), we have ...

18x +8(-3) = -6

18x = 18

x = 1

Finally, substituting into the equation for z gives ...

z = 4(1) +3(-3) +6 = 1

The solution is (x, y, z) = (1, -3, 1).

The equations can also be solved using Cramer's rule, elimination, matrix methods, and other means. When solving by hand, the method of choice will often depend on what you're familiar with and what the coefficients are.
