Answer:

I can't add picture for some reason so u have to read explanation :(

Step-by-step explanation:

First, turn everything into an improper fraction.

you get 11/3 x 9/2 ÷ 5/4

Next, according to PEMDAS, you multiply first and you get

33/2. DIvide that by 5/4 so

33/2 ÷  5/4

So you get 33/5 or as a mixed fraction, 6 3/5

Maria necesita un par de zapatos de tacon para un evento de gala y ya vio tres pares que le gustaron mucho cada uno cuesta $500,
Art [367]

Answer:

Mária debe trabajar mínimo 9 horas si quisiera tener la cantidad para pagar cualquiera de los pares de zapatos.

Step-by-step explanation:

Tenemos que calcular la cantidad de horas que tiene que trabajar María para alcanzar la cantidad de dinero necesaria para comprar alguno de los pares. La cantidad de dinero que Mária gana por trabajar x horas es 50.50*x. La cantidad total de dinero que tiene María está dada por 200+50.50*x (se le suma la cantidad que tiene ahorrada). Luego, basta con que esta cantidad sea mayor o igual al precio de cada par de zapatos.

Para hacerlo de manera más general, considerando unos zapatos que cuestan y, tenemos la siguiente inecuación

200+50.5x \geq y

Restando 200 a ambos lados y dividiendo por 50.5 obtenemos que

x \geq \frac{y-200}{50.5}

Basta reemplazar y por el valor de cada par de zapatos, para obtener su x correspondiente.

Si y = 500, entonces x \geq 5.94. Es decir, debe trabajar mínimo 6 horas.

Si y = 580 entoncesx \geq 7.52. Es decir, debe trabajar mínimo 8 horas

si y = 620 entoncesx\geq 8.31. Es decir, debe trabajar mínimo 9 horas.

Es decir que si quisiera tener la cantidad para pagar cualquiera de los pares, debe trabajar mínimo 9 horas.

40 pages = 80 minutes
210 pages = ? minutes
Well, take the first fact; 40 pages in 80 minutes and use it to find how many pages per minute.
40/80=1/2
1/2 pages = 1 minute
1 page = 2 minutes
210 pages = ? minutes
210*2=420
420 minutes = 7 hours
210 pages = 7 hours
Hope this helped :)

Find the value of x.
Nuetrik [128]
Because corresponding sides of similar figures are in proportion, we can obtain the equation:

(x+3)/4 = (2x-4)/3

Multiplying both sides by 12,

3(x+3)=4(2x-4)
3x+9=8x-16
x=5
