Given the equation 6x + 18 = 72: Part A: Write a short word problem about a purchase made to illustrate the equation. (6 points)
bulgar [2K]

Considering the linear function 6x + 18 = 72, it is found that:

A. The problem is: You made a number of services for $6, plus a base pay of $18, and earned $72. How many services you made?

B. The solution is: x = 9.

C. In the context of this problem, the solution means that you made 9 services.

<h3>What is a linear function?</h3>

The general format of a linear function is presented as follows:

y = mx + b.

In which the coefficients are:

  • m is the slope, representing  the variable amount, that is, by how much y changes when x is increased by one.
  • b is the y-intercept, which is the fixed amount.

In this problem, the equation is:

6x + 18 = 72.

From the given equation, considering the slope of 6 and the intercept of 18, the problem can be presented as follows:

You made a number of services for $6, plus a base pay of $18, and earned $72. How many services you made?

The solution is found isolating the variable x, as follows:

6x = 72 - 18

6x = 54

x = 54/6

x = 9.

The solution x = 9 represents the number of services that you made, in the context of this problem.

Se distribuyen 400 bolsas en tres urnas sabiendo que la primera tiene 80 menos que la segunda y esta tiene 60 menos que la terce
laiz [17]

Answer:

Primeras urnas = 60 bolsas

Segundas urnas = 140 bolsas

Terceras urnas = 200 bolsas

Step-by-step explanation:

Deje que las urnas se representen de la siguiente manera

Primeras urnas = a

Segundas urnas = b

Terceras urnas = c

Se nos dice en la pregunta

400 bolsas se distribuyen en tres urnas

Por lo tanto,

a + b + c = 400 bolsas ......... Ecuación 1

Por la pregunta sabemos que

1) El primero tiene 80 menos que el segundo

a = b - 80

2) Y este segundo tiene 60 menos que el tercero

b = c - 60

Por tanto, c = b + 60

Por lo tanto, sustituimos b - 80 por ayb + 60 por c en la Ecuación 1

a + b + c = 400 bolsas ......... Ecuación 1

b - 80 + b + b + 60 = 400 bolsas

Recopilar términos similares

b + b + b - 80 + 60 = 400 bolsas

3b = 400 + 80 - 60

3b = 420

b = 420/3

b = 140 bolsas

Por lo tanto, el número de bolsas en la segunda urna = 140 bolsas

Dado que a = b - 80

a = 140 bolsas - 80

a = 60 bolsas

Por lo tanto, el número de bolsas en la primera urna = 60 bolsas

Dado que c = b + 60

b = 140 bolsas

c = 140 + 60

c = 200 bolsas.

El número de bolsas en las terceras urnas = 200 bolsas.
