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]

Answer:

an=3+12n

Step-by-step explanation:

The sequence is

15, 27, 39, 51

The first term: a 1 = 15

The common difference of this sequence : d = 27 − 15 = 12

The nth term of an arithmetic sequence is given by formula

an=a+(n−1)d

So a n for this sequence will be:

an = 15 +(n−1) 12

an =(15)+12n−12

an = 3+12n

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

Answer:

14

Step-by-step explanation:

2 ( 4+3) = 2x7=14

Step-by-step explanation:

since the operation to solve for x is to divide both sides by 12, the opposite is multiplying by 12.

so, A is the correct answer.

Answer:

C) divide by 12

Step-by-step explanation:

'x' and 12 are getting multiplied

so to isolate 'x' you must do the inverse operation of multiplication, which is division

then you have x = 60/12 or x = 5

Answer: 5.4054%. Based on the given conditions, formulate: 37 - 35 / 37 Calculate the sum or difference: 2/37

The percentage of the propane that remains in the tank is 94.59%.

Given is that an empty propane tank weighs 17 pounds. A full propane tank weighs 37 pounds. Initially the propane tank weighs 35 pounds.

Let the total capacity of the tank be {x}.

For {x} = 0%, y = 17

For {x} = 100%, y = 37

Now,

100% of the filled tank weighs 37 pounds.

1 pound of the tank will be filled by : (100/37)% of propane

35 pounds of the tank will be filled by : {(100/37) x 35}% of propane

{(100/37) x 35}%

3500/37

94.59%

Therefore, the percentage of the propane that remains in the tank is 94.59%.

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

I believe your answer is:

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.

Answer:

3x+5y=20

Step-by-step explanation:

Answer:

3x + 5y = 20

Step-by-step explanation:

The given y = -3x/5 + 4 is in slope-intercept form.  We are to put it into standard form, which would be Ax + By = C.

Start by eliminating the fraction representing the slope (-3/5); to do this, multiply all three terms by 5:

5y = -3x + 20

Next, rearrange the terms to resemble Ax + By = C:

3x + 5y = 20

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
