Answer:
area = x² - 7x
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 2x and h = x - 7 , thus
A = [tex]\frac{1}{2}[/tex] × 2x(x - 7) = x(x - 7) = x² - 7x
Answer:
a=x^2-7x
Step-by-step explanation:
a=1/2bh
a=1/2(x-7)(2x)
a=1/2(2x^2-14x)
a=x^2-7x

There are 272 students in a school and there are 7 classrooms in total. If one classroom has
8 students and the rest of the classrooms have the same number of students, how many
students are there in each of the remaining 6 classrooms? Write and solve a two-step
equation to answer the question.
Answers
Answer:
6x + 8 = 272
44 students in each of the remaining 6 classrooms
Step-by-step explanation:
There are 7 classrooms.
1 classroom has 8 students.
The remining 6 classrooms have the same number of students each.
Let the number of students in each of the 6 classrooms be x.
In all 6 classrooms combined, there are 6x students.
Now add the 8 students of the 7th classroom.
The total number of students in all 7 classrooms is 6x + 8.
We are told there are 272 students in total, so we get the following equation.
6x + 8 = 272
Now we solve the equation.
Subtract 8 from both sides.
6x + 8 - 8 = 272 - 8
6x = 264
Divide both sides by 6.
6x/6 = 264/6
x = 44
There are 44 students in each of the 6 classrooms.

4 puntos) Una empresa dedicada a la venta de buzos en La Victoria, dispone para la confección de 500 m de tela algodón y 520 m de tela poliéster. Cada pantalón del buzo necesita 1 m de algodón y 2 m de poliéster; para cada casaca se necesitan 2 m de algodón y 1 m de poliéster. La ganancia por cada pantalón es de S/ 9 y la ganancia por cada casaca es de S/ 12. El fabricante sabe que sus máquinas en promedio demoran 4 minutos en confeccionar un pantalón y 10 minutos en confeccionar una casaca; él promete entregar un pedido en una semana trabajando sus máquinas de lunes a viernes 8 horas diarias.
a) Modele la función objetivo y elabore el SIL para las restricciones.
b) ¿Cuánto será el pedido máximo de buzos (casaca y pantalón) que podrá entregar en una semana de trabajo? ¿Cuánto será su ganancia máxima?
Answers
Answer:
a) Las restricciones limitantes son;
1) La duración de tiempo de 2400 minutos.
2) La tela límite (algodón) de 500 m
b) El número máximo de pedidos de buzos (chaquetas y pantalones) que podrá entregar en una semana de trabajo es de 166 pares de chaquetas y pantalones.
Su beneficio máximo es 32,2[tex]\bar 7[/tex]·S
Step-by-step explanation:
a) El número de horas al día que trabaja el fabricante = 8 horas
Dado que la máquina puede hacer pantalones en 4 minutos y chaquetas en 10 minutos
Sea x = la cantidad de pantalones hechos en un día, e y = la cantidad de chaquetas hechas en una semana
Tenemos;
4 · x + 10 · y = 8 × 60 × 5 = 2400
x = y
Por lo tanto;
4 · x + 10 · y = 4 · x + 10 · x = 14 · x = 2400
x = 2400/14 ≈ 171,43, por lo tanto, redondeamos hacia abajo para dar;
x = 171
Por lo tanto, el fabricante fabrica 171 pantalones y 171 chaquetas durante la semana.
El material requerido para el pantalón = 171 m de algodón y 342 m de poliéster.
El material requerido para la chaqueta = 342 m algodón y 171 m poliéster
Para el material, tenemos [
a = Algodón, b = Poliéster
a + 2 · b = x
2 · a + b = y
3 · a + 3 · b = x + y = 2 · x
Dado que se requiere igual longitud de algodón y poliéster, dado por el coeficiente de ayb, y que la longitud del algodón es 500 m, que es menor que la longitud del poliéster, tenemos;
El número máximo de pantalones y chaqueta completos = 500/3 = 166,67 m, que se redondea a 166 pares
b) El número máximo de pares de pantalones y chaquetas que el fabricante podrá entregar en una semana de trabajo = 166 pares
Por tanto, el beneficio máximo será
La ganancia máxima = 166 × (S / 9 + S / 12) = 581 · S / 18 = 32.2[tex]\bar 7[/tex]·S.
La respuesta a esta pregunta consiste en resolver un problema de Programación lineal ( Maximizando la ganancia de la semana).
La solución es:
x = 180
y = 160
z ( max) = 3540 $
La siguiente tabla ordena los datos del problema para la elaboración de las distintas restricciones y la formulación de la función Objetivo

Answers
Answer:
$8
Step-by-step explanation:
5x / 5 = x
40 / 5 = 8
Marisa’s mother contribution was $8 each month.
What is an expression?An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Given that, Marisa’s savings account can be represented by the expression 5x+40. Marisa saved the same amount x each month for a period of 5 months. Her mother contributed an additional amount each month to Marisa’s savings account.
The amount in Marisa's account after 5 months = 5x + 40
She has saved $x each month for 5 months, therefore, her saving = 5x
Her mother given her an additional amount each month which is here shown by 40,
Since, if in 5 months it became 40, therefore, each month mother gave her = 40 / 5 = 8
Hence, Marisa’s mother contribution was $8 each month.

A brother and sister are comparing their ages. The older sister is 8 years less than twice the brother’s age. The sum of their ages is 25 years. Let "x" be the age of the brother. Set up and solve an equation for x.
Answers
Answer:
The brother is 11 years and the sister 14 years
Step-by-step explanation:
Let x represent the age of the brother and let y represent the age of the sister. Since the sum of their ages is 25 years, the sum can be represented by the equation:
x + y = 25 (1)
The sister age is 8 years less than twice the brother’s age, this can be represented by the equation:
y = 2x -8
2x - y = 8 (2)
Solve equation 1 and equation 2 simultaneously. Add equation 1 and equation 2, this gives:
3x = 33
x = 33/3
x = 11 years
Put x = 11 in equation 1:
11 + y = 25
y = 25 - 11
y = 14 years
