Answer:

Suppose you had 25% of a number x.

We know that 25% is also 1/4 of a value, like x.

Then if we multiplied that by 4 then we would get the value of x, or any number.

Lin multiplies 7/8 times a number.the product is less than 7/8 . Which could be Lin’s number ?
igor_vitrenko [27]

Answer:

Any number less than 1

Step-by-step explanation:

Let x be the number Lin multiplies by 7/8. So, we have:

(7/8)*x < 7/8

We need to find the possible values for x. Lets start by dividing both sides of our inequality by (7/8) in order to get x alone on the left side.

(7/8)*x / (7/8) < (7/8)/(7/8)

Reordering:

(7/8) / (7/8) * x < (7/8)/(7/8)

As any number divided by itself (except from 0) is equal to 1:

x < 1

So, the number that Lin multiplied by 7/8 MUST be less than 1. This is evident, as any positive number multiplied by a number less than 1 will decrease, doesn't matter if its a negative or positive number.

So, such number is less than 1. Any number less than 1 could be Lin's number.

En la feria una pera tiene un valor de b pesos y una manzana cuesta 7 pesos menos.la señora Rina compro 4 peras y una manzana. E
marin [14]

Answer:

El total que la señora Rina pagó por sus frutas, en términos de b, es:

  • <u>5b - 7</u>

Step-by-step explanation:

Para resolver este ejercicio, primero sacaremos las variable que nos brindan:

  • Costo de la pera = b
  • Costo de la manzana = b - 7 (esto se debe a que la manzana cuesta 7 pesos menos que la pera, tal como dice el enunciado).

Ahora, nos centraremos en la compra realizada por la señora Rina, donde se menciona que:

  • <em>Compra de la señora Rina = 4 peras + 1 manzana</em>

Ahora, como si esto fuera una ecuación, vamos a reemplazar las manzanas y las peras por las variables que tenemos de su costo:

  • Compra de la señora Rina = 4b + b - 7

Y procedemos a operar:

  • <u>Compra de la señora Rina = 5b - 7</u> (sumando 4b + b)

Por lo tanto, <u><em>la compra de la señora Rina, en términos de b, le ha costado 5b - 7</em></u>.
