Answer:

k= -9

Step-by-step explanation:

2k-3=9k+63-3     [expand the 9(k+7) first]

2k-9k=63-3+3     [put the like terms together]

-7k=63                 [do the simple math]

k= 63 ÷ by -7

k=-9  

Answer:

K = -9

Step-by-step explanation:

2k-3 = 9(k+7)-3

2k-3 = 9k+63-3

2k-3 = 9k+60

2k-9k = 60+3

-7k = 63

-k = 9

k = -9

A pound of apples cost 3/4 of a dollar. How much do 5 pounds cost?

Step-by-step explanation:

Essentially you are buying 3/4s of 5 somethings. Since buying a partial of an object is not so common, we will do the inverse, where you buy 5 things, worth 3/4 of something

Answer:

Step-by-step explanation:

Using h, p, g, c to represent the values of the hat, pumpkin, ghost, and cauldron, respectively, we can write 5 equations:

Solving the last equation for h, and substituting into the first equation gives ...

  h = 19 -2g

  g(19 -2g) +(19 -2g) = 40

  2g^2 -17g +21 = 0 . . . . . . . . write in standard form

  (2g -3)(g -7) = 0 . . . . . . . factored form

The values of g that make the factors zero are g = 3/2 and g = 7. If we assume the solution is restricted to integer values, then g = 7, and ...

  h = 19 -2·7 = 5

From equation 4, ...

  5p +7 = 17   ⇒   p = 2

From equation 3, ...

  7 +2c = 27   ⇒   c = 10

The values of the symbols are ...

_____

Check

Equation 2 becomes ...

Answer:

3.5x10³

Step-by-step explanation:

7x10^5=700000

2x10^2=200

Divide both by 100

7000÷2=3500

divide by 1000 as standard form is less than 10

1000 is 10 cubed

3500÷1000 is 3.5

∴3.5x10^3 is answer

Considering that the sum of the internal angles of a triangle is of 180º, it is found that x = 20.

The sum of the measures of the internal angles of a triangle is of 180º.

In this problem, the angles are:

Hence:

[tex]46 + 71 + 4x - 17 = 180[/tex]

[tex]4x + 100 = 180[/tex]

[tex]4x = 80[/tex]

[tex]x = \frac{80}{4}[/tex]

[tex]x = 20[/tex]

I believe your answer is:  

[tex]y = 7x - 3\leftarrow \text{No.}\\\\y = 150x \leftarrow \text{Yes.}[/tex]

»»————-　★　————-««  

Here’s why:  

⸻⸻⸻⸻

[tex]\boxed{\text{General Proportional Formula:}}\\\\y = kx\\\rule{150}{0.5}\\$\bullet \text{ } k - \text{Constant of Proportionality}\\\rule{150}{0.5}\\\text{Since } y=150x \text{ is in this form, we can say that it is a proportional relationship.}\\\rule{150}{0.5}\\\text{We can also tell if something is proportional by graphing them.}[/tex]

[tex]\textbf{Proportional graphs go through the origin.}[/tex]

⸻⸻⸻⸻

Since y = 7x - 3 does not pass the origin, it is not proportional. However, y = 150x does, so it is proportional.
