ejemplo7 + 2 + 8.5 – 3.5

 

7 + 2 + 8.5 + (−3.5)

 

La propiedad asociativa no aplica a las expresiones de resta. Entonces, reescribe la expresión como la suma de un número negativo.

(7 + 2) + 8.5 + (−3.5)

 9   + 8.5 + (−3.5)

     17.5 + (−3.5)

     17.5 – 3.5 = 14

 

 

 

Agrupa 7 y 2, y súmalos. Luego, súmales 8.5. Finalmente, suma −3.5, que es lo mismo que restar 3.5.

Resta 3.5. La suma es 14.

7 + 2 + (8.5 + (−3.5))

7 + 2 +     5

 9  +     5

14

 

Agrupa 8.5 y –3.5, y luego súmalos para obtener 5. Luego suma 7 y 2, y súmalos al 5.

 

La suma es 14.

Respuesta    (7 + 2) + 8.5 – 3.5 = 14 y 7 + 2 + (8.5 + (−3.5))

saw5 [17]

Answer:

<u>Alejandro went to 8 matinee shows and 4 evening shows.</u>

<u>Our system of equations:</u>

<u>x + y = 12</u>

<u>7x + 12y = 104</u>

Correct statement and question:

Alejandro loves to go to the movies. He goes both at night and during the day. The cost of a matinee is 7 dollars. The cost of an evening show is 12 dollars.

Alejandro went to see a total of 12 movies and spent $ 104. How many of each type of movie did he attend? Write a system of equations.

Source:

Previous question that can be found at brainly

Step-by-step explanation:

Step 1:

Let x to represent the number of matinee shows Alejandro went to.

Let y to represent the number of evening shows Alejandro went to.

Now, let's write our system of equations:

x + y = 12

7x + 12y = 104

*********************

x = 12 - y

*********************

7 (12 - y) + 12y = 104

84 - 7y + 12y = 104

5y = 104 - 84

5y = 20

y = 20/5

<u>y = 4 ⇒ x = 12 - 4 = 8</u>

<u>Alejandro went to 8 matinee shows and 4 evening shows.</u>

Determine any data values that are missing from the table, assuming that the data represent a linear function.
Varvara68 [4.7K]

Answer:

c. 14

Step-by-step explanation:

Let the missing y value be y2.

If the data represent a linear function, then:

\frac{6 - 2}{2 - 1} = \frac{y_2 - 6}{4 - 2}

\frac{4}{1} = \frac{y_2 - 6}{2}

4 = \frac{y_2 - 6}{2}

Multiply both sides by 2

4 \times 2 = \frac{y_2 - 6}{2} \times 2

8 = y_2 - 6

Add 6 to both sides

8 + 6 = y_2 - 6 + 6

14 = y_2

The missing value is 14
