-1/2(2n + 4) + 6 = –9 + 4(2n + 1)
Answer: 1/3=n
Step-by-step explanation:
-1/2(2n + 4) + 6 = –9 + 4(2n + 1)
Distribute:
-1n-2+6=-9+8n+4
Combine like terms:
-1n-2+6=-9+8n+4
-1n+4=-5+8n
Add 1n on both sides:
-1n+4=-5+8n
-1n+1n+4=-5+8n+1n
4=-5+9n
Add 5 on both sides:
4+5=-5+5+9n
9=9n
Divide 9 on both sides:
9/9=9n/9
1=n

Let u = ⟨9, –2⟩, v = ⟨–4, 3⟩, and w = ⟨5, 1⟩. Kelcy incorrectly determined 3u – 5(v + w) to be ⟨32, –26⟩. Review her steps as shown.
3u – 5(v + w)
3⟨9, –2⟩ – 5[⟨–4, 3⟩ + ⟨5, 1⟩]
⟨27, –6⟩ – 5[⟨–1, 4⟩]
⟨27, –6⟩ + ⟨5, –20⟩
⟨32, –26⟩
What mistake did Kelcy make?
She added ⟨–4, 3⟩ and ⟨5, 1⟩ incorrectly.
She did not correctly distribute 3 to both components of u.
She should have distributed –5 to both v and w before adding.
She should have subtracted ⟨27, –6⟩ and ⟨5, –20⟩, rather than adding.
Answer:
A
Step-by-step explanation:
-4 +5 is 1 not -1 lol
The incorrect step where Kelcy did mistake is given by: Option A: She added ⟨–4, 3⟩ and ⟨5, 1⟩ incorrectly.
How to add two vectors?Suppose that two vectors are given as:
[tex]x = \: < a,b > \\y= \: < c,d >[/tex]
Then, their addition is given as:
[tex]x + y = \: < a +c , b + d >[/tex]
For this case, we can see that when Kelcy added <-4,3 > and <5,1>, she didn't add -4 and 5 correctly, as it results in +1, and not -1,
Thus, <-4,3> + <5,1> = <1,4>
Thus, wrong addition caused error in the solution.
Thus, the incorrect step where Kelcy did mistake is given by: Option A: She added ⟨–4, 3⟩ and ⟨5, 1⟩ incorrectly.

Answer:
6.75
Step-by-step explanation:
A of rectangle = 2*1.5=3
A or triangle= (7-2)*1.5/2 = 5*1.5/2 =3.75
Area trapezoid =A rectangle +Atriangle = 3+3.75=6.75
Answer:
C : 6.75 yd.
Step-by-step explanation:
first, you divide the trapezoid into two shapes, a square, and a triangle. For the square's area, you multiply 2yd and 1,5 yd to get 3 yd. Then for the triangle's area, since the bottom side of the trapezoid is a side for both the triangle and the square, the square already took 2yd if that makes sense. You multiply 5yd and 1.5 yd to get 7.5 yd. Since its a triangle, you divide the area of the triangle by 2, which is 3.75 yd. To get the total area of the trapezoid, you then add 3yd plus 3.75 yd to get 6.75 yd. ²

En una clase, 1/3 de los estudiantes eligieron estudiar español como segundo lenguaje vivo. 1/9 eligió italiano, el resto eligió alemán. Qué fracción de los estudiantes de la clase eligieron estudiar alemán? Si hay 15 estudiantes estudiar alemán, ¿cuántos estudiantes no estudian alemán?
Answer:
5/9
12
Step-by-step explanation:
La clase entera es 1.
1/3 estudian español.
1/9 estudian italiano.
1 - 1/3 - 1/9 estudian alemán.
1 - 1/3 - 1/9 = 9/9 - 3/9 - 1/9 = 5/9
5/9 de los estudiantes estudian alemán.
n = numero total de estudiantes en la clase.
5/9 n = 15
9/5 * 5/9 * n = 15 * 9/5
n = 27
Hay 27 estudiantes en la clase.
27 - 15 = 12

Answer:
17.5
Step-by-step explanation:
175% is written as 175/100. If you move the decimal at the end over twice you get 1.75/1 which is just 1.75. You then multiple 10 by 1.75 and you get 17.5
175% of 10 is

If the product (2x + 3)(x + k) is 2x2 + 13x + 15, what is the value of k?
Given:
The product [tex](2x + 3)(x + k)[/tex] is [tex]2x^2+13x+15[/tex].
To find:
The value of k.
Solution:
According to the question,
[tex](2x + 3)(x + k)=2x^2+13x+15[/tex]
Using distributive property, we get
[tex]2x^2+2xk+3x+3k=2x^2+13x+15[/tex]
[tex]2x^2+(2k+3)x+3k=2x^2+13x+15[/tex]
On comparing both sides, we get
[tex]3k=15\text{ and }2k+3=13[/tex]
[tex]k=\dfrac{15}{3}\text{ and }2k=13-3[/tex]
[tex]k=5\text{ and }2k=10[/tex]
[tex]k=5\text{ and }k=5[/tex]
Both value of k are same, i.e., 5.
Therefore, the value of k is 5.

Tyler bought 3 calculators and 7 pens for $67.80. Barbra bought 6 calculators and 2 pens for $92.40. How much does each pen cost?
Answer:
Each pen costs $3.60 (Each calculator costs $14.20).
Step-by-step explanation:
Let c represent calculator
Let p represent pen
3c + 7p = 67.8
6c + 2p = 92.4
Step 1: Solve 3c + 7p = 67.8 for c:
3c + 7p = 67.8
3c + 7p + −7p = 67.8 + −7p (Add -7p to both sides)
3c = −7p + 67.8
3c/3 = −7p + 67.8/3 (Divide both sides by 3)
c = −7/3p + 22.6
Step 2: Substitute −7/3p + 22.6 for c in 6c + 2p = 92.4:
6c+2p=92.4
6(−7/3p + 22.6) + 2p = 92.4
−12p + 135.6 = 92.4 (Simplify both sides of the equation)
−12p + 135.6 + −135.6 = 92.4 + −135.6 (Add -135.6 to both sides)
−12p = −43.2
−12p/−12 = −43.2/−12 (Divide both sides by -12)
p = 3.6
Step 3: Substitute 3.6 for p in c = −7/3p + 22.6:
c = −7/3p + 22.6
c= −7/3(3.6) + 22.6
c = 14.2 (Simplify both sides of the equation)
Answer:
c = 14.2 and p = 3.6
Hope this helps and have a great day :)

What are some of the cities where jazz first developed during the 1920s and 1930s? Why do you think these particular cities became important sites for jazz? From the timeline, on the left choose one subgenre of jazz and discuss what elements are found in this type of music. Choose one decade from the timeline on the left, and discuss how that particular decade influenced the development of jazz music. What is hard bop? What is jazz fusion? What is jazz like today? After listening to some of the music from different jazz composers, which one do you like the best? Why?
Answer:
1. Chicago, Detroit, Kansas City. Because they’re larger cities where pop culture thrives.
2. Hot Jazz. Hot Jazz is heavily dependant on improvisation. The key element of hot jazz was artists coming up with music on the spot and fast paced as well.
3. The roaring 20s had a huge impact on jazz. The roaring 20s was one of the first major revolutions in pop culture where people were turning away from traditional things and turning to new ideas, music, clothing, etc. This caused jazz to boom because it was a brand new style that was less constricted by society than music created prior to it.
4. A faster paced, more aggressive style of jazz.
5. A style of jazz that included many rock music characteristics.
6. Jazz, although less popular, can be found in lots of pieces today. It is either more modernized in new music, or is still the same as it was.
7. I like hot jazz the best because of the musical improvisation. I find it shows true talent the best in jazz musicians.
*The last questions not mentioned in the original question:
What are some ways that modern technology is used in music today that is different than music from when jazz originated? How do you think emerging technology will affect music in the future? - Music isn’t as real anymore. Most of today’s music in pop culture is produced by a computer rather than played live. Technology will, although continue to revolutionize music in the future, take away the element of true talent of music being played live like older jazz musicians once did.
According to Stefon Harris, what counts as a “mistake” in jazz? - Not incorporating or choosing to neglect other bandmate’s ideas when creating music.
