Answer:
Los procedimientos que se deben realizar para calcular la incógnita x en la ecuación 2x+5=7 son:
- <u><em>El 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual.</em></u>
- <u><em>El 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual.</em></u>
Step-by-step explanation:
Siguiendo los procedimiento descritos en la respuesta, para calcular el valor de la incógnita:
Seguimos el primer paso: <em>el 5 que está sumando a la izquierda del igual, se pasa a restar a la derecha del igual</em>:
Seguimos el segundo paso: <em>el 2 que multiplica a x a la izquierda del igual, se pasa a dividir a la derecha del igual:</em>
Como puedes ver, así se despejaría la incógnita x y solo faltaría operar los datos en la ecuación para obtener la respuesta:
<u><em>El resultado que nos daría la incógnita x sería 1</em></u>. Podemos probar el resultado en la ecuación original para comprobar el resultado que obtuvimos:
- 2x + 5 = 7
- 2 *(1) + 5 = 7
- 2 + 5 = 7
- 7 = 7
Así, identificamos que los procesos realizados fueron correctos.

To solve this question, we simply need to divide the total amount of students by 8% to find out how many students were absent and how many were present.
However, we can't simply multiply it by 8%, so we need to turn that into a decimal.
8% - 0.08
<em>Multiply:</em>
<em>355 x 0.08</em>
<em>= 28.4</em>
<em>Round:</em>
<em>28 kids were absent</em>
<em>Subtract:</em>
<em>355 - 28</em>
<em>= 327</em>
<em />
<em>This means that </em><em>28 kids were absent</em><em>, and </em><em>327 kids were present</em><em>.</em><em> </em>

Answer: Choice C
The probability of getting all heads is the same as the probability of getting all tails
=========================================================
Explanation:
H = heads
T = tails
In the first row, we have HHH to signify three heads. This shows up 1 time out of 8 outcomes total (each row is a different outcome). The probability of getting HHH is 1/8.
In the last row, TTT means we got three tails. Like with HHH, it only shows up once out of eight times, so the probability of getting TTT is 1/8 as well.
Therefore, both HHH and TTT have the same probability. This is because both sides of the coin have equal chances to land on. If the coin was more biased toward heads for example, then HHH and TTT would have different probabilities.
Answer:
x = rd/c
Step-by-step explanation:
xc = rd
xc/c = rd/c
x = rd/c
