adelina 88 [10]

Esto significa que debemos tener 58 páginas de plástico para contener las 517 tarjetas.´

<h3>¿Cuántas páginas se necesitarán para almacenar 517 tarjetas? </h3>

Sabemos que cada página puede almacenar hasta 9 cartas.

Entonces queremos ver cuantos grupos de 9 cartas hay en el conjunto de 517, para ver esto tomamos el cociente entre 517 y 9.

N = 517/9  = 57.44

Y no podemos tener un numero racional, así que debemos redondear al proximo número entero, que es 58.

Esto significa que debemos tener 58 páginas de plástico para contener las 517 tarjetas.

Solve the inequality.<br> 2(4+2x)&gt;5x+5<br> oxs-2<br> O X2-2<br> xs3<br> x23
mafiozo [28]

For this case we must resolve the following inequality:

2 (4 + 2x)> 5x + 5

Applying distributive property on the left side of inequality we have:

8 + 4x> 5x + 5

Subtracting 5 from both sides of the inequality:

8-5 + 4x> 5x\\3 + 4x> 5x

Subtracting 4x from both sides of the inequality:

3> 5x-4x\\3> x

Thus, the result is x

Answer:

x
