During a sales trip, Mr. Jones drove
15 miles east from Brownsville to
Carlton. Then he drove several more
miles east from Carlton to Sun City.
The distance from Brownsville to Sun
City is 35 miles. Write and solve an
addition equation to find how many
miles it is from Carlton to Sun City.

4. Acertijo.
7nadin3 [17]

Las edades de cada uno de los integrantes del acertijo son:

  • Luisa = 3 años
  • Juan = 6 años
  • Carmen = 8 años

Cálculo por medio de ecuaciones.

Para identificar la edad de cada persona en el acertijo, se pueden crear ecuaciones con la información brindada, aunque, primero se deben asignar variables:

  • <em>L = Edad de Luisa</em>
  • <em>J = Edad de Juan</em>
  • <em>C = Edad de Carmen</em>

Teniendo estas variables se procede a crear las ecuaciones, la primera parte del ejercicio dice que "<em>Luisa es 3 años más joven que su hermano Juan</em>", entonces la ecuación podría ser:

  • 1. J = L + 3

La segunda parte dice que "<em>su hermana Carmen es 2 años mayor que Juan</em>", entonces:

  • 2. C = J + 2

Y la tercera parte menciona que "<em>Juan tiene el doble de edad que Luisa</em>", por lo tanto:

  • 3. J = 2L

Se realiza el método de reducción con la primera y la tercera ecuación, para calcular el valor de L:

  • 1. J = L + 3 (<em>Se multiplica por (-1) puesto que la variable que se busca reducir es J</em>)
  • 3. J = 2L

Entonces se calcula:

  • - J = - L - 3
  •  J = 2L

 

  • 0 = L - 3 (<em>El número 3 que está restando se pasa a sumar al otro lado de la igualdad</em>)
  • 3 = L
  • <u>L = 3</u>

Teniendo el valor de L, se calcula el valor de J con la tercera ecuación:

  • J = 2L
  • J = 2 * 3
  • <u>J = 6</u>

Y con el valor de J, se calcula el valor de C con la segunda ecuación:

  • C = J + 2
  • C = 6 + 2
  • <u>C = 8</u>

De esta forma, se calcula que <u>las edades de Luisa, Juan y Carmen son: 3 años, 6 años y 8 años respectivamente</u>.

Can any two planes intersect?
andrey2020 [161]

Answer:

If two planes intersect, they intersect in a line. Two planes that do not intersect are called parallel. Given a plane and a line, there are three possibilities. The line and the plane intersect in a single point.

<span>the positive correlation between the height of a person and the number of times a person bumps their head on a low ceiling

Positive correlation means that when one factor increases, the other factor also increases and vice versa. 

Causation is a correlation wherein one factor is the main contributor of the other factor happening. In this case, the higher the height of a person is, the higher his chances of bumping his head on a low ceiling. </span>

The graph shown models a linear relation. Use the graph to answer the following questions. The two known points are (0, -3) and
Lady_Fox [76]

9514 1404 393

Answer:

  1. 3
  2. -1

Step-by-step explanation:

1. The value can be read from the graph. At 3 units to the right of the vertical axis, the line is 3 units above the horizontal axis. The independent variable has a value of 3 at that point.

__

2. The dependent variable has a value of -5 at the next grid line just below the bottom of the graph shown. The value of the independent variable is -1 at that point.
