An online games club charges $5.75 for the first game download and $2 for each additional
download per month. Write a rule for describing the total monthly fees f as a function of
additional downloaus d. What are the fees for 15 game downloads in a month?
Answer:
a) The rule is;
f = 5.75 + 2d
b) f = $33.75
Step-by-step explanation:
Here, we want to write a rule
The rule is that we have a standard download fee of 5.75 for the first download, and then a download fee of $2 per download for the rest
We have this as;
f = 5.75 + 2(d)
f = 2d + 5.75
Now for 15 downloads;
first download is $5.75, remaking 14 is at a rate of $2 per one
Thus, we have the fee value as;
f = 5.75 + 2(14)
f = 5.75 + 28 = $33.75

Answer:
x = 23
Step-by-step explanation:
This entire angle makes up 90° b/c of the square box
65 + x + 2 = 90
x + 67 = 90
x = 23
Answer: x=23
Step-by-step explanation:
This is a right angle. A right angle is 90°. It already gives us 65°. So 90-65=25°. We now know (x+2) ° = 25°. 25-2=23.
We can prove this is correct by answering the problem they gave us. (23+2) is 25. 25+65=90° 90° is a right triangle which also happens to be the triangle they have shown us.

Answer:
1. 8x + 3y - x - 2y
= 8x - x + 3y - 2y
= 7x + y
2. 3n - 7n - 2n + x + 8x
= 3n - 9n + 9x
= - 6n + 9x
3. 2r - 5n + 9y - 3r + n
= 2r - 3r - 5n + n + 9y
= -r - 4n + 9y
4. 12y - 6x + 5y - 3n
= 12y + 5y - 6x - 3n
= 17y - 9n
5. - 13n + 4n - r
= -9n - r
6. 7xy - 8x + 6xy - y
= 7xy + 6xy - 8x - y
= 13xy - 8x - y
7. - 14r - 10n - 3r - 9n
= -14r - 3r - 10n - 9n
= - 17r - 19n
8. 6r + 9r - 2r - 13n
= 6r + 7r - 13n
= 13r - 13n
9. n + r + x - 3x +4r
= n + r + 4r + x - 3x
= n + 5r - 2x
10. 15y - 7x + 9z + 4z - 3x

Answer:
a₆ = 972
Step-by-step explanation:
Is it correct?
a₄ = 3a₃ = 3 × 36 = 108
a₅ = 3a₄ = 3 × 108 = 324
a₆ = 3a₅ = 3 × 324 = 972
Answer:
Step-by-step explanation:
Remark
You could do this two ways: one with a formula and one without. I'll do it both ways.
With Formula
a_n = 4 * 3^(n - 1)
a_6 = 4 * 3^(5)
a_6 = 4 * 243
a_6 = 972
Without
a1 = 4
a2 = 4 * 3^(2 - 1)
a2 = 4 * 3
a2 = 12
a3 = 3* a_n-1
a3 = 3 * 12
a3 = 36
a4 = 3*a_3
a4 = 3*36
a4 = 108
a5 = 3 * a_(n - 4)
a5 = 3 * 108
a5 = 324
a6 = 3 * 324
a6 = 972 which is the same answer you got by using a formula
I need help please, If triangle JKL is congruent to QRS, find each missing value
Answer:
x = 5, y = 17, z = 8

Since the triangles are congruent to each other, corresponding angles and sides are congruent to each other.
JL corresponds with QS so...
3x - 1 = 14
3x = 15
x = 5
RS corresponds with LK so...
y + 10 = 27
y = 17
Angle L corresponds with angle S so...

Nicole is cooking cookies recipe calls for 5 cups of flour she has already put in three 1/3 cups how many more cups does she need to put in
Answer:
1 2/3 cups of flour
Step-by-step explanation:
Nicole is cooking cookies recipe calls for 5 cups of flour she has already put in three 1/3 cups how many more cups does she need to put in?
We solve the above question using Subtraction operation
The number of cups she still needs to put in =
5 cups - 3 1/3 cups
= 5 - 3 1/3
= 5/1 - 10/3
The Lowest Common Denominator = 3
= 15 - 10/3
= 5/3
= 1 2/3 cups of flour
Ian and Rachel each made a trail mix. The amounts of ingredients they have are shown. Ian used all of the coconut, dried cranberries, and dried bananas to make his trail mix. Rachel made 2 cups of trail mix containing all of the almonds, pumpkin seeds, and granola. How much trail mix did Ian make? How much more trail mix did Rachel make than Ian? Trail Mix Ingredients 4 cup almonds 4 cup pumpkin seeds 4cup coconut 4cup dried cranberries 1 4cup walnuts 1 cup granola4cup dried bananas
Answer:
The values written as Trail mix ingredients is not well written below is the trail mix ingredients
answer :
i) Ian made : 1 3/4 cups of trail mix
ii) Racheal made 1/4 more cup of trail mix
Step-by-step explanation:
Given that :
Trail Mix Ingredients
3 /4 cup almonds
1 /4 cup pumpkin seeds
2 /4 cup coconut
3 /4 cup dried cranberries
1 2 /4 cup walnuts
1 cup granola
2 /4 cup dried bananas
i) Ian used all of coconut , dried cranberries and dried Bananas
= 2/4 + 3/4 + 2/4
Amount of trail mix made = 7/4 = 1 3/4 cups
ii) Racheal made 2 cups of trail mix containing ; all almonds , pumpkin seeds and granola
= 3/4 + 1/4 + 1 = 2 cups of trail mix
Hence Racheal made ( 2 - 1 3/4 ) more trail mix than Ian
= 1/4 more cup of trail mix was made by Racheal
Jeremiah loves playing basketball. Of 13 shots taken, Jeremiah has made 12. He wants to increase his success rate to more than 95%. Write a function that could display this.
Answer:
The function for the success rate is given as follows;
[tex]The \ success \ rate \ function \ is \, f(x) = \dfrac{12+x}{13+x} \times 100[/tex]
Step-by-step explanation:
The number of shots Jerimiah made = 12 shots
The number of shots Jerimiah takes = 13 shots
[tex]The \ success \ rate = \dfrac{The \ number \ of \ shots \ made}{The \ number \ of shots \ taken} \times 100[/tex]
The current success rate is given as follows;
[tex]The \ success \ rate = \dfrac{12}{13} \times 100 \approx 92.31 \%[/tex]
Let 'x' represent the number of more shots Jerimiah has to make to have a success rate of 95%, we get;
[tex]The \ success \ rate \ function, \, f(x) = 95\% = \dfrac{12+x}{13+x} \times 100[/tex]
0.95·(13 + x) = 12 + x
12.35 + 0.95·x = 12 + x
0.35 = 0.05·x
x = 0.35/0.05 = 7
Therefore, Jeremiah has to make the next seven shots to have a success rate of 95%

Mr. White is renting an medium truck for one week and a few additional days d. He does not have to pay a per mile fee. Evaluate the expression 421 + 130d to find how much he will pay for a 12-day rental.
Answer:
1,981
Step-by-step explanation:
Total rental cost = 421 + 130d
d = 12
Total rental cost = 421 + 130(12)
= 421 + 1,560
= 1,981
He will pay a total of 1,981 for a 12-day rental.

De las 30 preguntas del examen de matematicas, por cada respuesta correcta se obtenian 5 puntos y por cada respuesta incorrecta, o pregunta no contestada,se perdian 2 puntos teodolindo obtuvo 94 puntos en este examen ¿cuantas respuestas correctas tuvo?
Answer:
Teodolindo obtuvo 22 respuestas correctas y 8 respuestas incorrectas o no contestadas.
Step-by-step explanation:
Un sistema de ecuaciones lineales, también conocido como sistema lineal de ecuaciones o simplemente sistema lineal, es un conjunto de ecuaciones lineales (es decir, un sistema de ecuaciones en donde cada ecuación es de primer grado), en el cual se relacionan dos o más incógnitas.
En los sistemas de ecuaciones, se debe buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en ambas ecuaciones.
En este caso se debe establecer un sistema de ecuaciones, donde las variables son:
x: cantidad de respuestas correctasy: cantidad de respuestas incorrectas o no contestadasSiendo 30 preguntas en el examen, se tiene la ecuación:
x + y= 30
Por cada respuesta correcta se obtenían 5 puntos y por cada respuesta incorrecta o pregunta no contestada, se perdían 2 puntos. Teodolindo obtuvo 94 puntos en este examen. Entonces se representa esta situación mediante la expresión:
5*x - 2*y= 94
Entonces el sistema de ecuaciones a resolver es:
[tex]\left \{ {{x+y=30} \atop {5*x-2*y=94}} \right.[/tex]
El método de sustitución consiste en despejar o aislar una de las incógnitas (por ejemplo, x ) y sustituir su expresión en la otra ecuación. De este modo, obtienes una ecuación de primer grado con la otra incógnita, y . Una vez resuelta, calculas el valor de x sustituyendo el valor de y calculado.
Entonces, despejando el valor de x de la primer expresión obtienes:
x= 30 -y
Reemplazando en la segunda ecuación obtienes:
5*(30 -y) - 2*y= 94
Resolviendo:
5*30 - 5*y - 2*y= 94
150 - 5*y - 2*y= 94
- 5*y - 2*y= 94 -150
-7*y= -56
y= (-56)÷(-7)
y= 8
Reemplazando el valor de y obtenido en la expresión x= 30 -y se obtiene:
x= 30 - 8
x=22
Teodolindo obtuvo 22 respuestas correctas y 8 respuestas incorrectas o no contestadas.
