En una jornada cultural los grupos de 3.° de ESO van a grabar un cortometraje y un clip musical. Al principio se inscribió para el corto el triple de alumnos que para el clip. A última hora, 5 alumnos se cambian del corto al clip y ahora el número de alumnos para el clip es la mitad que para el corto. ¿Cuántos están ahora en cada actividad?
Respuesta:
20 estudiantes
Explicación paso a paso:
Dejar :
número de estudiantes que firmaron para el clip = x
Número de estudiantes que firmaron para cortometraje = 3x
En el último minuto ;
Se convierte en cortometraje; 3x - 5 y el clip se convierte en; x + 5
Por eso ; la ecuación se convierte en;
x + 5 = 1/2 (3x - 5)
x + 5 = 1,5 x - 2,5
x - 1,5x = - 2,5 - 5
- 0.5x = - 7.5
x = 7,5 / 0,5
x = 15
Por lo tanto ;
Cortometraje: 1/2 (3x - 5)
1/2 (3 (15) - 5))
1/2 (45 - 5)
1/2 (40)
= 20
Por tanto, hay 20 alumnos en cada actividad.

Two parallel lines have same slopes so we need to find the slope of the line which passes through the given points.
Suppose : A = ( - 2 , 7 ) & B = ( 4 , 4 )
Slope = y ( B ) - y ( A ) / x ( B ) - x ( A )
Slope = 4 - 7 / 4 - ( - 2 )
Slope = - 3 / 4 + 2
Slope = - 3 / 6
Slope = - 1 / 2
------------------------------------------------------------
As you know The coefficient of x is the slope of the line in slope-intercept form.
Thus we have to find the option which x has - 1 / 2 as the coefficient .
Look we have that in D so the correct answer is D .
I don’t know how to do that
Answer:
16
Step-by-step explanation:
Divide 64 by 8 to get 8. this is 1/8 of the books.
3/8 were non fiction, or 24
1/4 (2/8) were picture books, or 16
5/8 were non fiction or picture books, so ’the rest‘ of the chapter books is 3/8.
3/8 were chapter books, or 24.
add the amount of picture books and chapter books since they are the fictional texts.
16+24=40
subtract the amount of non fictional books from the amount of fictional books to get the sum.
40-24=16

Step-by-step explanation:
the cost of a school banquet is $95 plus $15 for each person attending. Write an equation that gives total cost as a function of the number of people attending. What is the cost for 77 people?
Answer:
equation: y=15x+95
it would cost $1250
Answer:
f(x) = 95 + 15x
Cost for 77 people = $1250
Step-by-step explanation:
15 x 77 = 1155
1155 + 95 = 1250
2. What is the coordinate of the final image of vertex T
after the triangle is translated 3 units to the left and 2
units up?
Please help with number 2
Answer:
We have the coordinates of vertex T after the translation as (-5,0)
Step-by-step explanation:
Firstly, we get the coordinates of vertex T
we have this as;
(-2,-2)
Translating to the left means we are going to subtract the specific units from the x-coordinate
2 units up means we are going to add to the y-coordinate value
So, we have it that;
(-2-3, -2+ 2) = (-5,0)
Which of the following examples has a unit rate of 25 feet per second? Select all that apply. A) 100 feet in 4 seconds B) 150 feet in 10 seconds C) 225 feet in 9 seconds D) 275 feet in 11 seconds E) 100 feet in 5 seconds
Answer:
A) C) D)
Step-by-step explanation:
We can simply divide them to find out the answer.
A) 100/4=25
B)150/10=15
C)225/9=25
D)275/11=25
E)100/5=20

Simon bought a 10-pound bag of cat food. He gives his cat 0.3 pound of food per day. Which equation with two variables to describe how the amount of cat food in the bag changes over time.
Answer:
y = 10 - 0.3t
Step-by-step explanation:
Amount of cat food purchased= 10 pounds
Daily pounds fed to dog = 0.3 pounds
How the amount of cat food in bag changes over time ;
Let y = amount of cat food left in bag
t = number of days since cat food was purchased
Amount of cat food left in bag = amount of cat food purchased - (daily pounds fed to dog * Number of days since cat food was purchased)
y = 10 - 0.3t

Which measures describe the variation on a data set? a. Mean b. Median c. Mode d. MAD e. Interquartile range f. Range
Answer:
e, f
Step-by-step explanation:
A measurement of variability is an overview of the amount of dispersion in a dataset. The measures that can describe the variation on a data set are Range, Interquartile Range, Variance, and Standard Deviation.
So ,The among the given options the e. Interquartile range f. Range
Range of dataset is the difference between the larges and smallest elements in the dataset .
The middle of the data between the upper and lower quartiles are called the inter-quartile range. That means that 50 percent of data points between Q1 and Q3 are included within the interquartile range.
