A number, y, is equal to twice the sum of a smaller number and 3. The larger number is also equal to 5 more than 3 times the sma
Nata [24]

Answer:

The equations represent the situation is y=2x+6 and y=5+3x.

Step-by-step explanation:

Consider the provided information.

First convert the statement into mathematical representation.

Consider the smaller number is <em>x</em> and the larger number is <em>y</em>.

<em>y</em>, is equal to twice the sum of a smaller number and 3.    

This information can be written as: y=2(x+3)

Which can be further solve as:

y=2x+6

The larger number is also equal to 5 more than 3 times the smaller number.

This information can be written as: y=5+3x

Thus, the equations represent the situation is y=2x+6 and y=5+3x.

Which can be further solve as:

2x+6=5+3x

x=1

Now, substitute the value of <em>x</em> in y=5+3x.

y=5+3

y=8

Se requiere dos personas para construir una barda de 20 m de largo y 1.5 m de alto en dos días ¿cuántas personas se necesitan pa
Wewaii [24]

Answer:

Definamos R como la "velocidad" a la que una persona puede construir la barda dada.

Supongamos que la persona necesita un tiempo T para construir la barda, entonces tenemos la relación:

R*T = 1 barda.

Si dos personas trabajan juntas la velocidad de trabajo va a ser (R + R), y sabemos que ellos pueden completar el trabajo en 2 días, entonces:

(R + R)*2 días = 1 barda

(2*R)*2 días = 1 barda

(2*R) = (1/2) barda por día

R = (1/2)*(1/2) barda por día = (1/4) barda por día.

Esto significa que una persona puede completar un cuarto de la barda en un día de trabajo.

Ahora queremos saber cuantas personas se necesitan para construir una barda en solo medio día, entonces debemos resolver:

(N*R)*0.5 días = 1 barda

Donde N es el número de personas que queremos obtener.

(N* (1/4) barda por día)*0.5 días = 1 barda

N*(1/4) barda por día = (1/0.5) bardas por día = 2 bardas por día

N = 2/(1/4) = 2*4 = 8

N = 8

Se necesitan 8 personas para construir una barda en medio día.
