Answer:
Inequality to determine number of glass sets: 10x + 230 ≥ 498
Solved inequality: x ≥ 26.8 (She needs to buy at least 27 sets)
Step-by-step explanation:
In order to write an inequality to represent this situation, you must first identify the important information:
- The restaurant needs 498 glasses total at the least
- They already have 230 glasses
- Each set of glasses has 10 glasses
Now, you can write an inequality to represent this situation:
498 (needed glasses) ≤ 230 (glasses already owned) + 10x (number of glasses in one set (x))
You can rewrite it as 10x + 230 ≥ 498 so that x is on the left and it is ordered by variable exponential value. Now you have the inequality to represent the situation, so to find the number of sets of glasses Brooklyn could buy, you need to isolate x:
10x + 230 ≥ 498 (given)
10x ≥ 268 (subtract 230 from both sides)
x ≥ 26.8 (divide both sides by 10)
So, Brooklyn needs to buy at least 27 sets since she can't buy 4/5 of a set.
Answer:
Los números son 6 y 9
Step-by-step explanation:
Este problema se puede resolver por medio de un sistema de ecuaciones.
El primer número será x y el segundo número será y.
Sabemos que los dos números suman 15, por lo tanto esto se puede escribir como:
Por otro lado sabemos que el doble de uno de ellos es igual al otro más 3 unidades, esto lo podemos escribir de la siguiente manera:
(el doble del primero es igual al segundo más 3)
Reescribiendo esta segunda ecuación tenemos:
Por lo tanto, nuestras dos ecuaciones son:
Resolviendo el sistema por el método de reducción observamos que, si sumamos ambas ecuaciones, las y se cancelan y quedamos con:
Ahora, sustituimos este valor en la primera ecuación para obtener el valor de y:
Por lo tanto, los números son 6 y 9
The correct answer is D or the last option
Answer:
6%
Step-by-step explanation:
450.5 - 425 = 25.5
25.5/425= .06
.06 times 100 = 6
Answer:
C is the answer
Step-by-step explanation:
