I need an answer for "−12x+y=10"

Step-by-step explanation:

Perimeter means the sum of all the three side of triangle perimeter= x + x+ 5 + x +7 =3x +12

Answer:

All exterior angles will add up to 360 degrees, regardless of the number of sides.

For the sum of the interior angles, use this formula:

The sum of the interior angles = (N x 180) - 360

Where N = the number of sides

So, (40 x 180) - 360 = 6840 degrees

The measure of each interior and exterior angle of a regular 40-gon are [tex]171^\circ[/tex] and [tex]9^\circ[/tex] respectively.

Important information:

Interior angle of a regular polygon is [tex]\dfrac{(n-2)\times 180^\circ}{n}[/tex], where n is the number of sides.

A regular 40-gon has 40 sides. So, the measure of each interior angle is:

[tex]\dfrac{(40-2)\times 180^\circ}{40}=38\times 4.5^\circ[/tex]

[tex]\dfrac{(40-2)\times 180^\circ}{40}=171^\circ[/tex]

Exterior angle of a regular polygon is [tex]\dfrac{360^\circ}{n}[/tex], where n is the number of sides.

A regular 40-gon has 40 sides. So, the measure of each exterior angle is:

[tex]\dfrac{360^\circ}{40}=9^\circ[/tex]

Therefore, the measure of each interior and exterior angle of a regular 40-gon are [tex]171^\circ[/tex] and [tex]9^\circ[/tex] respectively.

Answer:

(5, 2) & (-4, -9)

Step-by-step explanation:

Use the vertex form, y = a(x − h)² + k, to determine the values of a, h, and k

(h, k) = (5, 2)

(h, k) = (-4, -9)

Answer:600 students

Step-by-step explanation:

Answer:

There are 600 students participating. The operation you have to carry out is 800 × .75 = 600.

Or you can simply divide 800÷4= 200. 3/4=200×3. The percentage of students is 3/4 that would be 600 students participating.

Answer:

x = 24

Step-by-step explanation:

[tex]20 - \frac{x}{3} = \frac{x}{2}[/tex]

[tex]40 - \frac{2x}{3} = x[/tex]

[tex]120 - 2x = 3x\\120 = 5x\\x = 120 /5\\x = 24[/tex]

Answer:

Number of cupcakes = 2

Number of cookies = 5

Step-by-step explanation:

Let [tex]x[/tex] denotes the number of cupcakes and [tex]y[/tex] denotes the number of cookies.

Abigail bought $11.25 worth of cupcakes and cookies such that each cupcake costs $3.75 and each cookie costs $0.75.

[tex]3.75x+0.75y=11.25[/tex]

At [tex]x=0;[/tex] [tex]0.75y=11.25[/tex]

[tex]y=\frac{11.25}{0.75} =15[/tex]

At [tex]y=0;3.75x=11.25[/tex]

[tex]x=\frac{11.25}{3.75}=3[/tex]

So, plot the points [tex](0,15)\,,\,(3,0)[/tex]

Also,

Abigail bought a total of 7 cupcakes and cookies altogether.

[tex]x+y=7[/tex]

At [tex]x=0;0+y=7[/tex]

[tex]y=7[/tex]

At [tex]y=0;x+0=7[/tex]

[tex]x=7[/tex]

So, plot points [tex](7,0)\,,\,(0,7)[/tex]

From the graph, solution is [tex](2,5)[/tex]

Number of cupcakes = 2

Number of cookies = 5

Answer:

$7,719.33

Step-by-step explanation:

$24,500 x 0.06 = $1,470

($24,500 + $1,470) x 0.06 = $1,558.20

($24,500 + $1,558.20) x 0.06 = $1,563.49

($24,500 + $1,563.49) x 0.06 = $1,563.81

($24,500 + $1,563.81) x 0.06 = $1,563.83

$1,470 + $1,558.20 + $1,563.49 + $1,563.81 + $1,563.83 = $7,719.33
