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.

masha68 [24]

<u>Solution-</u>

1.

Bill bought a computer and a printer for a total of $650.

Let p stand for the cost of the printer, so

\text{Cost of the computer + p} =650

\Rightarrow 525+p=650

\Rightarrow p=650-525=125

2.

Bonnie ordered 27 products from one company

Let m stand for the number of missing items

\text{Number of item she got + m} =27

\Rightarrow 19+m=27

\Rightarrow m=27-19=8

3.

Terri bought four lipsticks for a total cost of $20

Let l stand for the cost of one lipstick.

Price\ of\ one\ lipstick \times I=20

\Rightarrow 4 \times I=20

\Rightarrow I=5

4.

Each survey takes him about 10 minutes to complete

Let h stand for the number of hours

Tota\l time\ taken\ = Time\ taken\ for\ 1\ survey\ in\ hours\times no.\ of\ survey

Total\ time\ taken\ =\frac{10}{60} \times 30 = 5 hours

5.

Andy played golf three times during his vacation. His scores were 92, 87, and 88.

Let A stands for the average.

Average \ score=A= \frac{Score_1+Score_2+Score_3}{3} =\frac{92+87+88}{3}=89

6.

Tickets to a local basketball team’s games cost $12 each. Brendon and Ed each bought tickets to four games.

Total tickets = 2×4=8 (∵ They each bought 4 tickets)

(Let t stand for the amount spent on tickets.

Amount\ spent\ on\ tickets\ =price\ of\ 1\ ticket \times total\ ticket}

\Rightarrow t=12 \times 8=96

How many solutions can be found for the equation −4x − 11 = 2(x − 3x) + 13?
Virty [35]
0, No solution.
-4x-11=2 (x-3x)+13
-4x-11=2 (-2x)+13
-4x-11=-4x+13
-11 is not equal to 13 so there is no solution
