160. 80 is half of 160.

Well if it is on sale for $80 and it is half-off, that means that the original price is $160 because 80/2 is 160.

Scilla [17]

15x-24

the answer is not B because 3*-5= -15, we need -24

the answer is not C because 3*-24= -72

the answer is not A because 5*8= 40

Answer :

D. 3(5x − 8)

La edad de juan es un año menos que la tercera parte de la edad de la madre. si dentro de 5 años, la edad de la madre sera 10 añ
koban [17]

Usando un sistema de ecuaciones, se encuentra que Juan tiene 12 años e su madre tiene 39 años.

<h3>¿Qué es un sistema de ecuaciones?</h3>

Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.

En este problema, las variables son:

  • Variable x: Edad de Juan.
  • Variable y: Edad de su madre.

La edad de juan es un año menos que la tercera parte de la edad de la madre, por eso:

x = \frac{y}{3} - 1

Dentro de 5 años, la edad de la madre sera 10 años mas que el doble de juan, por eso:

y + 5 = 2(x + 5) + 10

y + 5 = 2x + 20

Como x = \frac{y}{3} - 1:

y + 5 = \frac{2y}{3} + 18

3y + 15 = 2y + 54

y = 39

x = \frac{y}{3} - 1 = \frac{39}{3} - 1 = 13 - 1 = 12

Juan tiene 12 años e su madre tiene 39 años.

Mrrafil [7]
Since the cost of the telephone cost is 25 cents per minute, and by using the variable you provided, "t", the equation thus far is 25t=cost, or 25 multiplied by "t".

Since the telephone also charges 75 cents at the start, we just have to add it into our equation, making 75+25t=cost of telephone call in cents.

answer: 75+25t=cost of telephone call in cents
