Answer:

V = 8

Step-by-step explanation:

Answer:

30

Step-by-step explanation:

y = kx

k= y/x

k= 45/5

k= 9

Therefore the value of x can be calculated as follows

k= y/x

x= y/k

x= 270/9

x= 30

Answer:

94

I don't really have much else to say but I need 20 characters so y'know :/

Answer:

15.45

Step-by-step explanation:

103x0.15=15.45

Answer:

Do 103 times 0.15 and you get 15.45

Step-by-step explanation:

Answer:

No.

Step-by-step explanation:

Let's substitute the given coordinate pair into each inequality:

[tex]y > 2x+6\\-4 > 2(-5)+6\\-4 > -10+6\\-4 > -4\rightarrow\text{Not true!}[/tex]

Since this coordinate pair does not satisfy the inequality (note the coordinate pair must satisfy BOTH inequalities), therefore (-5, -4) is not a solution to this system of inequalities.

Using a system of equations, it is found that Kayla will pay $54.25 for 5 adult tickets and 4 children tickets.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

Amy bought 2 adult tickets and 4 children tickets for $35.50, hence:

2x + 4y = 35.50

x + 2y = 17.75

x = 17.75 - 2y

Jane bought 3 adult tickets and 3 children tickets for $36.0, hence:

3x + 3y = 36

x + y = 12

From the first equation:

17.75 - 2y + y = 12

y = 5.75.

x = 17.75 - 2 x 5.75 = 6.25.

Hence the total paid for Kayla is given by:

T = 5 x 6.25 + 4 x 5.75 = $54.25.

Answer:

18

Step-by-step explanation:

3x + 28 = 46

Subtract 28 from each side

3x + 28 = 46

3x+28-28 = 46-28

3x=18

Divide each side by 3

3x/3 = 18/3

x = 6

Find 2x+6

2(6)+6

12+6

18

Hey there!

3x + 28 = 46

SUBTRACT 28 to BOTH SIDES

3x + 28 - 28 = 46 - 28

CANCEL out d 28 - 28 because it give you 0

KEEPs 46 - 28 because it help solve for the x-value.

NEW EQUATION: 3x = 46 - 28

SIMPLIFY IT!

3x = 18

DIVIDE 3 to BOTH SIDES

3x/3 = 18/3

CANCEL out: 3/3 because it give you 1

KEEP: 18/3 because it give you the x-value.

NEW EQUATION: x = 18/3

SIMPLIFY IT!

x = 6

Now that we have your x-value we can substitute it into the equation of: 2x + 6

SIMPLIFYING:

2x + 6

= 2(6) + 6

= 12 + 6

= 18

Thus, your answer is: 18

Good luck on your assignment & enjoy your day!

Answer:

[tex]\displaystyle Inconsistency\:[No\:Solution][/tex]

Step-by-step explanation:

We need to isolate one pair of variables so they are set to zero. Now, in this case, we need to split one of the equations in negative half, so we will select the second equation:

[tex]\displaystyle \left \{ {{3x - 2y = 8} \atop {6x - 4y = 12}} \right. \\ \\ \\ \left \{ {{3x - 2y = 8} \atop {-\frac{1}{2}[6x - 4y = 12]}} \right. \\ \\ \left \{ {{3x - 2y = 8} \atop {-3x + 2y = -6}} \right. \\ \\ \\ \boxed{0 \ne 2}[/tex]

The fact that we have a result like this proves that we cannot obtain a solution from this system, which means that on a graph, these equations are considered parallel [no intersection, so no solution].

p=3829.39

ur welcome

Answer:

p = 10

Step-by-step explanation:

10p - 3 = 2(12 + 4p) - 7

First, distribute within the parenthesis

10p - 3 = 24 + 8p - 7

Combine like terms

10p - 3 = 17 + 8p

Subtract 8p from both sides of the equation

2p - 3 = 17

Add 3 to both sides of the equation

2p = 20

Divide both sides by 2 to get your answer:

p = 10

10 packages

First find the perimeter

perimeter = 2 × (length+width)

2 × (20 + 40)

2 × 60 = 120

4 yards = 12 feet

120 ÷ 12 = 10 packages

-2 < x/3 + 1 < 5

Subtract 1 from each side:

-2 - 1 < x/3 + 1 - 1 < 5 - 1

-3 < x/3 < 4

Multiply each side by 3:

-3 • 3 < x/3 • 3 < 4 • 3

Answer:

k = - 2

Step-by-step explanation:

( 2x - y )²

Formula : -

( a - b )² = a² + b² - 2ab

Here,

a = 2x

b = y

( 2x - y )²

= ( 2x )² + y² - 2 ( 2x ) ( y )

= 4x² + y² - 4xy

So,

( 2x - y )² = 4x² + y² - 4xy

( 2x + y )²

Formula : -

( a + b )² = a² + b² + 2ab

Here,

a = 2x

b = y

( 2x + y )²

= ( 2x )² + y² + 2 ( 2x ) ( y )

= 4x² + y² + 4xy

So,

( 2x + y )² = 4x² + y² + 4xy

( 2x - y )² - ( 2x + y )²

= 4x² + y² - 4xy - ( 4x² + y² + 4xy )

= 4x² + y² - 4xy - 4x² - y² - 4xy

= 4x² - 4x² + y² - y² - 4xy - 4xy

= 0 + 0 - 8xy

= - 8xy

( 2x - y )² - ( 2x + y )² = 4xyk

- 8xy = 4xyk

Divide 4xy on both sides,

- 8xy / 4xy = 4xyk / 4xy

- 2 = k

k = - 2

Therefore, the value of k is - 2.
