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.
I may be an Ambitious, but due to my absence from Brainly a while back I am no longer an Ace, like I used to be.
Ella has 5 nickels and 7 quarters.
7 quarters is equal to $1.75.
5 nickels is $0.25
$1.75 + $0.25 = $2.00
Step 1: Subtract 3x from both sides.
−x+7=−52
Step 2: Subtract 7 from both sides.<span><span><span><span>
−x</span>+7</span>−7</span>=<span><span>−52</span>−7</span></span><span><span>
−x</span>=<span>−59</span></span>
Step 3: Divide both sides by -1.<span><span><span>
<span><span>−x</span><span>−1</span></span></span></span>=<span><span><span><span>−59</span><span>−1</span></span></span></span></span><span>
x=59</span>
Sample answer: <span>For </span>f<span>(3), the input is 3 and you are looking for the output. To determine the function's value when </span>x<span> = 3, go to the value of 3 on the </span>x<span>-axis and then locate the graph for that value of </span>x<span>. Determine the value of </span>y<span> from the </span>y<span>-axis at that location on the graph.
Hope this helps
