Answer:
The correct answer is A.
Step by step:
Here is A: 4x > 22; x = 5.8
First, you replace the x with 5.8.
Since the 4 and the x are touching that means to multiply.
So, multiply 4 and 5.8 which results in 23.2.
If you replace the 4x with 23.2 this statement is true meaning that A is the correct answer for this problem.
6/15 in simplest form is 2/5.
Divide the numerator and denominator by 3. :)

Answer:
El precio de la entrada al cine es de <em>$56</em>
Step-by-step explanation:
Cada uno de los 4 amigos las 2 veces por semana consumen un paquete de palomitas que cuesta: $28 ; entonces debemos multiplicar el costo de las palomitas por las dos veces que las consumen para saber el costo total de las palomitas:
28 x 2 =$56
El ejercicio nos dice que al no comer esas dos veces palomitas pueden ingresar a cine una tercera vez por semana ,lo que significa que al no pagar los $56 en palomitas podrán pagar una tercera entrada,lo que quiere decir que la entrada a cine es de $56.
Entonces podemos hacer la siguiente relación matemática: <em> Precio total de las palomitas dos veces por semana = Precio de la entrada a cine</em>.
To solve this question, you need to know the rate in which the money is being spent. First, you know the y-intercept, which is 4000, or the money she owned before spending it. Next, you know, how much she had spent in the duration of 3 months. So, if you substitute those numbers into y=ax+b, it would be 2800=-3a+4000 (or 2800=4000-3a either way it is equivalent) If you solve this, you know that the college freshman is spending her money at a rate of $400 per month. Hope this helps :)
