Answer 1

Answer:

n = -6

x = -7

n = 27

Step-by-step explanation:

Question 1

-3n - n + 12 = 36

First we get all the variables to one side using subtraction property of equality.

-3n - n + 12 (-12) = 36 (-12)

-4n = 24

divide by the coefficient of n to isolate the variable

-4n/-4 = 24/-4

n = -6

Question 2

-2x - 3x - 15 = 20

-5x - 15 = 20

-5x = 35

x = -7

Question 3

3 + n/9 = 6

Isolate the n variable

n/9 = 6 - 3

multiply by 9

n = 27

Answer 2

Answer:

1. n = -6

2. x = -7

3. n = 27

A) x = 44

B) x = 16

C) x = 22

D) x = 66

Answers

Answer:

C)  x = 22

Step-by-step explanation:

3x + 3x + 48 = 180

6x = 180 - 48

x = 132 / 6

x = 22

The answer is x=22 (C)

Which of the equations are true identities? \begin{aligned} \text{A. }&(y+6)(y-7)+42=y^2-y \\\\ \text{B. }&(x+3)(x-8)=x^2-5x \end{aligned} A. B. ​ (y+6)(y−7)+42=y 2 −y (x+3)(x−8)=x 2 −5x ​

Answers

Answer:

Only A, the first equation is true.

Step-by-step explanation:

A. (y + 6)(y – 7) + 42 = y² + 6y –7y – 42 + 42 = y² – y. This means A is true

B. (x + 3)(X – 8) = x² + 3x – 8x – 24 = x² – 5x – 24. This means B is false.

The length of a room is 4 feet less than twice its width. The perimeter of the room is 58 feet. What is the length of the room?

Answers

Answer:

Length = 18

Step-by-step explanation:

Length= 2w - 4

Perimeter= 58

Perimeter= 2L + 2w

58 = 2(2w-4) + 2w

58 = 4w -8 + 2w

58 = 6w - 8

66 = 6w

11 = w

Plug in width to find the variable L

58 = 2L + 2(11)

58 = 2L + 22

36 = 2L

18 = L

Reflect Here are two paint mixtures: • $$3 cups of white and $$4 cups of blue. • $$6 cups of white and $$8 cups of blue. Both mixtures make the same color because they are in equivalent ratios. Which of these mixtures is also in an equivalent ratio? $$ white $$ blue $$ white $$ blue $$ white $$ blue $$ white $$ blue

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

Mixture 1:

[tex]White = 3[/tex]     [tex]Blue = 4[/tex]

Mixture 2:

[tex]White = 6[/tex]     [tex]Blue = 8[/tex]

Required

Determine equivalent mixtures

First, we need to calculate the unit rate of the given mixtures using:

[tex]Rate = \frac{White}{Blue}[/tex]

For mixture 1:

[tex]Rate = \frac{3}{4} = 0.75[/tex]

For mixture 2:

[tex]Rate = \frac{6}{8} = 0.75[/tex]

So, to determine which other mixture has equivalent ratio.

All you need to do is divide the number of white cups by the number of blue cups.

Since the options are not clear enough, I'll assume the following:

[tex]White = 12[/tex]      [tex]Blue =16[/tex]

The rate will be:

[tex]Rate = \frac{12}{16} = 0.75[/tex]

Any rate other than 075 is not equivalent
