Polygon Diagonals. The number of diagonals in a polygon = n(n-3)/2, where n is the number of polygon sides. For a convex n-sided polygon, there are n vertices, and from each vertex you can draw n-3 diagonals, so the total number of diagonals that can be drawn is n(n-3).

Step-by-step explanation:

27 divided by 3 is 9, 27/3=9 because 27/3 is the same exact thing as 27 divided by 3. So the answer has to be 9

Answer:

P(x)=2x-60

Step-by-step explanation:

From the information provided, the function P(x) would indicate that the total profit you earned from selling x cups of lemonade is equal to the result of multiplying the price per cup for the number of cups minus the total cost. This cost is the result of adding up the cost of buying wood plus the cost per cup for the number of cups:

P(x)=5x-(60+3x)

P(x)=5x-60-3x

P(x)=2x-60

According to this, the function is: P(x)=2x-60.

Answer:

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

Step-by-step explanation:

Solve the following system by substitution.

2x – 3y = –2

4x +   y = 24

The idea here is to solve one of the equations for one of the variables, and plug this into the other equation. It does not matter which equation or which variable you pick. There is no right or wrong choice; the answer will be the same, regardless. But — some choices may be better than others.

For instance, in this case, can you see that it would probably be simplest to solve the second equation for "y =", since there is already a y floating around loose in the middle there? I could solve the first equation for either variable, but I'd get fractions, and solving the second equation for x would also give me fractions. It wouldn't be "wrong" to make a different choice, but it would probably be more difficult. Being lazy, I'll solve the second equation for y:

4x + y = 24

y = –4x + 24

Now I'll plug this in ("substitute it") for "y" in the first equation, and solve for x:

2x – 3(–4x + 24) = –2

2x + 12x – 72 = –2

14x = 70

x = 5

Answer: No

Step-by-step explanation:

Yes, the two ratios 4:6 and 6:9 are equal to 2:3.

A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six.

Given that there are two ratios 4:6 and 6:9. The equivalence of the two ratios will be calculated as:-

4 : 6 = ( 2 x 2 ) ÷ ( 2 x 3 )

4 : 6 = 2 : 3

6:9 = ( 2 x 3 ) ÷ ( 3 x 3 )

6: 9 = 2 : 3

4 : 6 = 6:9 = 2:3

Therefore, the two ratios 4:6 and 6:9 are equal to 2:3.

Answer: The angles inside a triangle are called interior angles. ... The three interior angles in a triangle will always add up to 180°. At each corner the exterior and interior angles are on a straight line, so at each corner these two angles add up to 180°.

Step-by-step explanation:

Sal proves that the angles of an equilateral triangle are all congruent (and therefore they all measure 60°), and conversely, that triangles with all congruent angles are equilateral.

Answer:

  40 months

Step-by-step explanation:

Let t represent the number of months. Then Greg's tie count (g) will be ...

  g = 30 + t/4 . . . . . . average rate of tie accumulation is 1/4 tie per month

And Mark's time count (m) will be ...

  m = t . . . . . . . . . . . . average rate of tie accumulation is 1 per month

We want these numbers (g, m) to be equal:

  g = m

  30 +t/4 = t . . . . . substitute the equivalent expressions

  30 = 3/4t . . . . . . subtract t/4

  40 = t . . . . . . . . . multiply by 4/3

After 40 months, Mark and Greg will have the same amount of ties.

                               Question 9:

Given the equations

[tex]5x+2y=6;[/tex]

[tex]4x-8y=0[/tex]

solving the system of the equations

[tex]\begin{bmatrix}5x+2y=6\\ 4x-8y=0\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}5x+2y=6\mathrm{\:by\:}4\:\mathrm{:}\:\quad \:20x+8y=24[/tex]

[tex]\mathrm{Multiply\:}4x-8y=0\mathrm{\:by\:}5\:\mathrm{:}\:\quad \:20x-40y=0[/tex]

[tex]\begin{bmatrix}20x+8y=24\\ 20x-40y=0\end{bmatrix}[/tex]

[tex]20x-40y=0[/tex]

[tex]-[/tex]

[tex]\underline{20x+8y=24}[/tex]

[tex]-48y=-24[/tex]

[tex]\begin{bmatrix}20x+8y=24\\ -48y=-24\end{bmatrix}[/tex]

[tex]-48y=-24[/tex]

[tex]\frac{-48y}{-48}=\frac{-24}{-48}[/tex]

[tex]y=\frac{1}{2}[/tex]

[tex]y = 0.5[/tex] ( 0.5 is the result of rounding 0.5 to the nearest 0.01)

[tex]\mathrm{For\:}20x+8y=24\mathrm{\:plug\:in\:}y=\frac{1}{2}[/tex]

[tex]20x+8\cdot \frac{1}{2}=24[/tex]

[tex]20x+4=24[/tex]

[tex]\frac{20x}{20}=\frac{20}{20}[/tex]

[tex]x=1.00[/tex] ( 1.00 is the result of rounding 1 to the nearest 0.01 )

So, the solution is:

(x, y) → (1.00, 0.5)

                            Question 10)

Similarly the question 10 can be solved.

Given the equations

[tex]5x+2y=9;\:4x-3y=44[/tex]

solving

[tex]\begin{bmatrix}5x+2y=9\\ 4x-3y=44\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}5x+2y=9\mathrm{\:by\:}4\:\mathrm{:}\:\quad \:20x+8y=36[/tex]

[tex]\mathrm{Multiply\:}4x-3y=44\mathrm{\:by\:}5\:\mathrm{:}\:\quad \:20x-15y=220[/tex]

[tex]\begin{bmatrix}20x+8y=36\\ 20x-15y=220\end{bmatrix}[/tex]

[tex]20x-15y=220[/tex]

[tex]-[/tex]

[tex]\underline{20x+8y=36}[/tex]

[tex]-23y=184[/tex]

[tex]\begin{bmatrix}20x+8y=36\\ -23y=184\end{bmatrix}[/tex]

[tex]-23y=184[/tex]

[tex]y=-8.00[/tex]   ( -8.00 Rounded to the nearest 0.01 or  the Hundredths Place )

[tex]\mathrm{For\:}20x+8y=36\mathrm{\:plug\:in\:}y=-8[/tex]

[tex]20x+8\left(-8\right)=36[/tex]

[tex]20x=100[/tex]

[tex]x=5.00[/tex]  ( 5.00 Rounded to the nearest 0.01 or  the Hundredths Place )

So, the solution is:

(x, y) → (5.00, -8.00)
