N-the number

n + 65 = 3n - 45 |subtract 65 from both sides

n = 3n - 110 |subtract 3n from both sides

-2n = -110 |divide both sides by (-2)

n = 55

Answer:

1.25 cups

Step-by-step explanation:

Since you have 5 5/8 cups = 4 1/2 water bottles

you can make it

5.625 cups = 4.5 water bottles

Then, all you have to do is divide both sides of this equation by 4.5, so

5.625 / 4.5 = 1 water bottle

1.25 cups = 1 water bottle

zhuklara [117]

Answer:

The surface area of door is 33 680 cm².

Step-by-step explanation:

Given that the surface area of a cuboid which is the 3D of rectangle is :

$s.a = 2(l \times w) + 2(l \times h) + 2(w \times h)$

$let \: l = 80 \\ let \: w = 3 \\ let \: h = 200$

$s.a = 2(80 \times 3) + 2(80 \times 200) + 2(3 \times 200)$

$s.a = 2(240) + 2(16000) + 2(600)$

$s.a = 480 + 32000 + 1200$

$s.a = 33680 \: {cm}^{2}$

Given: an n-gon Prove: The sum of the measures of the interior angles is 180(n – 2)°. Complete the missing parts of the paragrap

icang [17]

Given: an n-gon

Prove: The sum of the measures of the interior angles is 180(n – 2)°.

Complete the missing parts of the paragraph proof.

We are given an n-gon, which has n sides and n vertices.

Answers:

1. If we choose one of the vertices, we can draw n-3 diagonals.

2. These diagonals form n-2 triangles.

3. The sum of the interior angle measures of a triangle is 180 degrees.

4. n – 2 triangles would have an interior angle measure sum of 180 degrees.

5. Therefore, the sum of the measures of the interior angles of an n-gon is 180(n – 2)°.
