Answer:

B :step 2   she didnt collect all the like terms and calculate

Step-by-step explanation:

first rewrite  remove all (  )Parentheses

2nd   collect all like terms and calculate

a^4 + 7a -16 -12^a^3 + 5a -3

a^4 + 12a - 19 - 12a^3     ( Like terms are 7a +5a  and -16 +-3)

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

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

12 estudiantes no estudian alemán.

Answer:

213.28 in^2

Step-by-step explanation:

surface area = 2(LW + LH + WH)

surface area = 2[(4.4 in)(5.6 in) + (4.4 in)(8.2 in) + (5.6 in)(8.2 in)]

surface area = 213.28 in^2

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.

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.

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
