The phrase "the sum of four and twice a number is 12" can be translated into an algebraic expression as: 4 + 2x = 12 or 2x + 4 = 12.
<h3>How to Translate a Phrase into an Algebraic Expression?</h3>
To translate the phrase into an algebraic expression, we can use a variable to represent the unknown number.
Let the unknown number be represented as: "x".
"Sum" means addition, which would be represented with the symbol, "+".
"Twice" means times 2.
Therefore, we can translate the given phrase into an algebraic expression as follows:
"twice a number" is translated as: 2x
The sum of four (4) and twice a number (2x) is translated as: 4 + 2x or 2x + 4.
Therefore, the whole phrase "the sum of four and twice a number is 12" would be translated into an algebraic expression as: 4 + 2x = 12 or 2x + 4 = 12.

Answer:
children's: 111 and adults: 62
Explanation:
- given total number of people 173
- total amount received is $306
- during the process, we shall consider x as children and y as adult
make equations:
x + y → 173 [ this was from total people ]
1.5x + 2.25y → $306 [ this was from cost ]
try to make x the subject:
x + y → 173
x → 173 - y ______equation 1
1.5x + 2.25y → $306
1.5x → 306 - 2.25y
x → 
__________equation 2
solve them simultaneously:
= 173 - y
306 - 2.25y = 259.5 - 1.5y
-2.25 + 1.5y = 259.5 - 306
-0.75y = -46.5
y = 62
so there were total 62 adults that day in the public swimming pool.
find children's using:
x → 173 - y
x → 173 - 62
x → 111
so there were total 111 children's that day in the public swimming pool.
Answer:
Don Alfredo debe pagar $272,200 para encerrar por completo el corral.
Step-by-step explanation:
Dado que Don Alfredo quiere construir un corral cuadrado para sus gallinas, utilizando metros de malla lineal para rodearlo, si el zootecnista le recomendó construir uno que tenga 121 metros cuadrados, para determinar cuánto dinero debe pagar don Alfredo en la ferretería para encerrar por completo el corral si el metro lineal de malla tiene un valor de $ 6.200 el metro se deben realizar los siguientes cálculos:
121 metros cuadrados = √121 = 11 (x 11) = 11 x 4 = 44 metros lineales
44 x 6,200 = X
272,800 = X
Por lo tanto, Don Alfredo debe pagar $272,200 para encerrar por completo el corral.
