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.

The square root is 4/9 which equals what???
Romashka [77]

Answer:

Square roots are a number multiplied by the same number.

Therefore 2 x 2 = 4

3 x 3 = 9

To simplify this fraction as a square root, they are both perfect squares so the answer would be 2/3

Bernard solved the equation 5 x + (negative 4) = 6 x + 4 using algebra tiles. Which explains why Bernard added 5 negative x-tile
LenaWriter [7]

Answer:

To find why he would do this, we need to understand what all the possible first steps are in this equation.

You could add 4 to both sides.

You could subtract 4 from both sides.

You could subtract 5x from both sides.

You could subtract 6x from both sides.

Any of these work. In Bernard's case, he added 5 negative x tiles, meaning he subtracted. C and D already make no sense, but allow me to further explain. By him subtracting 5x from both sides, the equation turns into:

-4 = x + 4

By this point, he can just subtract 4 from both sides to find the value of x. But the question asks for why he did the first step. Therefore, it would
