Answer:

x = -2

Step-by-step explanation:

3(5x + 2) = 2(3x - 6)

<em>Expand the brackets. </em>

15x + 6 = 6x - 12

<em>Isolate the unknown variable x. </em>

15x - 6x = -12 - 6

<em>Evaluate. </em>

9x = -18

<em>Find x. </em>

x = -18 ÷ 9

x = -2

The scale on a map is 55 cm: 88 km. If the distance between two cities is 5656 km, how far apart in cm are the two cities on the
Alinara [238K]

Answer:

3,535 cm

Step-by-step explanation:

55cm=88km

Let's make that "one unit" - 55cm=1 unit. How many units are in the distance 5656km?

5656km/88km=64.2727... units.

55cmx64.2727... = 3,534.999 cm (depending on what your teacher requires, we can probably round to 3,535).

Therefore, we know that the two cities are 3,535 cm apart on the map.

A 20-sided regular polygon has an angle measure represented as 3gº.
Andre45 [30]

The value of g in the 20 sided regular polygon is 54.

<h3>How to find the angles of a regular polygon?</h3>

If all the polygon sides and interior angles are equal, then they are known as regular polygons.

The polygon given is a 20 sided regular polygon and the measure of each angle is 3g degrees.

Therefore, let's find g.

The sum of interior angles of a 20 sided polygon is as follows:

180(n - 2) = 180(20 - 2) = 180(18) = 3240

Therefore,

each angle = 3240 / 20 = 162

Hence,

162 = 3g

g = 162 / 3

Therefore,

g = 54
