<h2>Respuesta:</h2>

1513

<h2>Explicación paso a paso:</h2>

En este problema, estamos hablando del autoretrato de Leonardo Davinci. Para la resolución de este problema, necesitamos usar el cuadrado mágico de forma tal que al colocar en cada casilla los números del 1 al 16 sin repetición, entonces los números de cada fila, columna y diagonal sumen 34. De esta manera, si se colocan los números así, el resultado obtenido es 34. En la figura de abajo se encuentra el cuadrado mágico resuelto:

Columna 1:

1 + 15 + 10 + 8 = 34

Columna 2:

3 + 13 + 6 + 12 = 34

Columna 3:

14 + 4 + 11 + 5 = 34

Columna 4:

16 + 2 + 7 + 9 = 34

Fila 1:

1 + 3 + 14 + 16 = 34

Fila 2:

15 + 13 + 4 + 2 = 34

Fila 3:

10 + 6 + 11 + 7 = 34

Fila 4:

8 + 12 + 5 + 9 = 34

Diagonal 1:

8 + 6 + 4 + 16 = 34

Diagonal 2:

1 + 13 + 11 + 9 = 34

Finalmente, esta pintura fue realizada en el año 1513, que son los números de las casillas en negro.

A pool pass costs $30 for the first month and $15 each additional month. Construct an explicit rule in function notation to mode
noname [10]

Answer:

F(n)=15(n+1)    [ where n is number of months]

F(12)=195

Step-by-step explanation:

Pool pass cost for first month =$30

Pool pass cost after first month = $15 for each month

The total amount charged by the pool can be expressed as a  function F(n) where n represents the number of months.

F(n)=15(n-1)+30

This can be simplified by using distribution.

F(n)=(15n-15)+30

F(n)=15n-15+30

F(n)=15n+15

Take 15 as greatest common factor.

∴ F(n)=15(n+1)

For n=12

F(12)=15(12+1)

F(12)=15(13)

F(12)=195

∴ Amount charged by pool for 12 months = $195

0.13 over 0.2 turned into a decimal
fredd [130]
The answer is 0.65
This is the same as 1.3/2 since the decimal must be moved one place to the right for both divisor and dividend.

3(x-4) = 2(-2x + 1)<br>this is confusing me​
nata0808 [166]

Answer:

x = 2

Step-by-step explanation:

<em>Distribute</em>

3 (−4) = 2 (−2+1)

3 − 12 = 2 (-2x +1)

<em>Distrubute again</em>

3x - 12 = -4x + 2

<em>Add twelve to both sides of the equation</em>

<em>Simpfly</em>

3x = -4x + 14

<em>Add 4x to both sides of the equation</em>

<em>simpfly</em>

7x = 14

<em>Divide both sides of the equation by the same term</em>

<em>Simpfly</em>

x = 2
