Comprás 4 libras de arroz con 10$.¿Cuántos necesitas para 14 libras?​
Fofino [41]

Answer:

Alegría puede comprar 16.667 libras de arroz y 12.5 libras de azúcar con 20 pesos.

Step-by-step explanation:

Sabemos que una libra de arroz cuesta 0.60 pesos, mientras que una de azúcar cuesta 0.80 pesos. Un enfoque posible es determinar cuantas libras de arroz se obtiene por el mismo dinero para adquirir una libra de azúcar a través de una regla de tres simple:

Esto quiere decir que por cada tres libras de azúcar, se compra cuatro libras de arroz. Ahora, la cantidad de alimentos que puede comprar Alegría queda restringida al dinero disponible (20 pesos) y se describe por la siguiente ecuación:

(Ec. 1)

Donde:

- Cantidad de arroz, medida en libras.

- Cantidad de azúcar, medida en libras.

Además, la siguiente ecuación se deriva de la regla de tres del inicio del problema:

(Ec. 2)

Si aplicamos (Ec. 2) en (Ec. 1) y resolvemos la ecuación resultante, tenemos que:

De (Ec. 2) tenemos que la cantidad de arroz es:

En consecuencia, Alegría puede comprar 16.667 libras de arroz y 12.5 libras de azúcar con 20 pesos.

PLEASE HELP !! ILL GIVE BRAINLIEST *EXTRA POINTS*.. <br> IM GIVING 40 POINTS !! DONT SKIP :((.
Anna71 [15]

Answer:

m = 1/3

b = -6

Step-by-step explanation:

How to calculate slide (m):

\frac{y_{1} - y_{2} }{x_{1} - x_{2} } = m

x1 = 0

x2 = -12

y1 = -6

y2 = -10

If we put in the values:

\frac{(-6) - (-10)}{0 - (-12)} = m

Subtracting a negative number is the same as adding it:

\frac{(-6) + 10 }{0 + 12} = m

-6 + 10 = 4 and 0 + 12 = 12 so now we have this:

\frac{4}{12} = m

Lets simplify:

4 and 12 can both be divided by 3:

\frac{1}{3}  = m

3 and 1 are prime numbers and cannot be simplified further.

Now we know that m=1/3

Since:

y = mx + b

y = -6

x = 0

m = 1/3

Then:

-6 = 1/3*0 + b

1/3*0 is 0, so we can just remove that part:

-6 = b

that means b is equal to -6

Hope i was able to help!
