Pregunta completa :
Wolfrich vivió en Portugal y Brasil para aprender portugués durante un período de 14 meses. Aprendió un promedio de 130 palabras nuevas por mes cuando vivió en Portugal y un promedio de 150 palabras nuevas cuando vivió en Brasil. En total aprendió 1920 palabras nuevas. ¿Cuánto tiempo vivió Wolfrich en Portugal y cuánto tiempo vivió en Brasil?
Responder:
Portugal = 9 meses
Brasil = 5 meses
Explicación paso a paso:
Dado que:
Total de meses pasados tanto en Brasil como en Portugal) 14 meses
Dejar ;
tiempo pasado en Brasil = b
Tiempo pasado en Portugal = p
Promedio de palabras aprendidas por mes en Brasil = 150
Promedio de palabras aprendidas por mes en Portugal = 139
Total de palabras aprendidas = 1920
Matemáticamente;
150b + 130p = 1920 - - - (1)
b + p = 14 - - (2)
b = 14 - p
De 1)
150 (14 - p) + 130p = 1920
2100 - 150p + 130p = 1920
2100 - 20p = 1920
2100 - 1920 = 20p
180 = 20p
p = 9
b = 14 - p
b = 14 - 9
b = 5
Por lo tanto;
Portugal = 9 meses
Brasil = 5 meses
what are the steps to solve
|x|=9
Answer:
9 or -9
Step-by-step explanation:
the lines surrounding x are absolute value, which gets rid of negative and positives and simply ask the distance from x on a number line if the absolute value of x is 9, then x is 9 places away from 0 on the number line, so it could be 9 or -9

Decompose and use the distributive property to find the product of 9 × 8.53.
76.77
72.72
76.5
79.2
Answer:
First option. 76.77
Step-by-step explanation:
The distributive property of the multiplication with respect to the sum can be written as:
[tex]x ( y + z ) = xy + xz[/tex]
We can take advantage of this property to find the product of 9*8.53 if we write:
8.53 = 8 + 0.53, thus:
[tex]9*8.53=9*(8+0.53)[/tex]
Applying the distributive property:
[tex]9*8.53=9*8+9*0.53[/tex]
Operating:
[tex]9*8.53=72+4.77=76.77[/tex]
Thus:
9*8.53=76.77
First option. 76.77
Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs \$3.25$3.25dollar sign, 3, point, 25. Then, he wants to buy as many pancakes as he can, but he wants his bill to be at most \$30$30dollar sign, 30 before tax. The restaurant only sells pancakes in stacks of 444 pancakes for \$5.50$5.50dollar sign, 5, point, 50.
Answer:
C. 3.25 + 5.50S ≤ 30
Step-by-step explanation:
The given parameters are;
Chocolate milk = $3.25
A stack of four pancakes = $5.50
Number of pancakes in one stack = 4
Let
S = number of stacks of pancakes Benjamin buys
Cost of the pancakes Benjamin buys = $5.5 × S
= 5.5S
The maximum amount Benjamin wants his bill to amount to = $30
The inequality is
Cost of chocolate milk + Cost of pancakes Benjamin buys ≤ $30
$3.25 + $5.50S ≤ $30
3.25 + 5.50S ≤ 30.
Option C is the correct answer
C) C 3.25 + 5.50 S ≤ 30
3.25+5.50S≤303, point, 25, plus, 5, point, 50, S, is less than or equal to, 30

Answer:
90°
Step-by-step explanation:
The sum of angle 2 and angle 3 is equal to 90° because ABC is a right triangle.
Answer:
90
Step-by-step explanation:
This is a special right triangle. Now, the angles 1 is 90 degrees that means we have another 90 degrees left. We don't even need to add to know the total of angles 2 and 3 are 90 because every triangle is 180 degrees and every right angle is 90.
At Park Junior High, 10%, or 160, of the students, play a musical instrument. How many students attend the school?

There are 1,600 students in the school.
There are 250 students in the school.
The number of students in the school are represented by percentages
The number of students in the school is 1600
Let the number of students in the school be n.
So, the equation from the question is:
[tex]\mathbf{10\% \times n = 160}[/tex]
Divide both sides by 10%
[tex]\mathbf{n = \frac{160}{10\%}}[/tex]
Express 10% as decimal (0.10)
[tex]\mathbf{n = \frac{160}{0.10}}[/tex]
[tex]\mathbf{n = 1600}[/tex]
Hence, the number of students in the school is 1600
