what is the value of k in the following equation?
12+k/22=13

Answer:

Volume is dependent on how hard the air is pushed through. Sound travels more slowly than light. Sound waves travel at the same speed, but vibrate in different ways. Some vibrate quickly and have a high frequency or pitch, while others vibrate slowly and give a lower pitch.

Answer:

x= 8

Step-by-step explanation:

Step 1- Distribute into the parenthesis by 1.

4x+2+3(-1)+3(-1)x= 7

Step 2- Simplify.

4x+2-3-3x= 7

Step 3- Add common variables.

(4x-3x)+(2-3)

1x-1= 7

Step 4- Add 1 to both sides.

1x-1= 7

 +1  +1

1x= 8

Step 5- Divide both sides by 1.

1x= 8

1    1

x= 8

Can you give me a Brainliest

plz plz plz plz plz plz

Answer:x=8

Step-by-step explanation:

4x+2-(3+3x)=7

Distribute -1 in parentheses because there is an invisible 1

4x+2-3-3x=7

Combine like terms

X-1=7

Add one on both sides

x=8

Answer:

Midpoint of (-6, 3) and (8, -7) is: (1, -2)

Step-by-step explanation:

Given the points

Computing the midpoint of (-6, 3) and (8, -7) using the formula

⇒  [tex]\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-6,\:3\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)[/tex]

⇒  [tex]\left(\frac{8-6}{2},\:\frac{-7+3}{2}\right)[/tex]

⇒  [tex]\left(1,\:-2\right)[/tex]

Therefore, Midpoint of (-6, 3) and (8, -7) is: (1, -2)

Answer:

The total cost of an item can be calculated by adding the sales tax to the retail cost:

Step-by-step explanation:

Sales tax = 7%

                = 7/100

                 = 0.07

Total cost of an iten can be calculated by adding the sales tax to the retail cost.

i.e. c + .07c

Therefore, the total cost of an item can be calculated by adding the sales tax to the retail cost:

Answer:

B. 56°

Step-by-step explanation:

[tex] 20 \degree = \frac{1}{2} (96 \degree - \widehat{LN}) \\ \\ 2 \times 20 \degree = (96 \degree - \widehat{LN}) \\ \\ 40 \degree = (96 \degree - \widehat{LN }) \\ \\ \widehat{ln} = 96 \degree - 40 \degree \\ \\ \huge \red{ \widehat{LN} = 56 \degree}[/tex]

Step-by-step explanation:

Answer:

Option (B)

Step-by-step explanation:

Since the linear graph is passing through the origin, there is a proportional relationship between the amount of chocolate (C) and amount of peanuts (P) used in the package of snacks mix,

P ∝ C

P = kC

k = [tex]\frac{P}{C}[/tex]

Here k = proportionality constant

Since, the given line passes through a point (3, 2),

k = [tex]\frac{2}{3}[/tex]

Therefore, ratio of chocolate and peanuts mixed is [tex]\frac{2}{3}[/tex].

Option (B) is the correct option.

Answer:

$15.98

Step-by-step explanation:

25% off means it is 75% of its normal cost

0.75 x 20 = 15

The scarf is $15 after 25% discount. Then we calculate its final cost after tax:

6.5% = 0.065

1.065 x 15 = 15.975 which rounds to $15.98

Answer: 15.98

Step-by-step explanation: 25% off 20 is 15. 6.5% times 15 is .98 so the answer is 15.98

Answer:

the ordered pair will be (1, 2)

Step-by-step explanation:

first of all substitute the x and y values into the equation in other to make the equation true.

Therefore y=4x-7

1 = 4(2) -7

1 = 8 -7

1 = 1

Making the first equation true. then move to the second equation which is y = - x + 3

1 = -(2) + 3

1 = 1

Answer:

32+10=7x

Step-by-step explanation:

Let's solve this first. 32$ is the final price, and then add 10$ because of the gift card, leaving you with 42$. Divide the 42 by 7, because each CD is 7 dollars. The result is 6. So put that into an equation.

32+10=42=7x

x=6!

Answer: x/2

Step-by-step explanation:

A unknown number can be represented by a variable (‘x’ in this case) and the unknown number (x) is being divided by 2, therefore its x/2

Answer:

3/5

Step-by-step explanation:

y=3/5x = 0                 x both sides by 5

5y-3x=0                     reorder terms (community property)

-3x+5y=0

3x-5y=0                                changes the signs when you do that
