Answer:

Step-by-step explanation:

3x-5=1x+25 add 5 to both sides

3x=1x+30 subtract 1x from both sides

2x=30 divide both sides by 2

x=15

4x=2y-12, using x=15

4(15)=2y-12

2y-12=60 add 12 to both sides

2y=72 divide both sides by 2

y=36

So x=15 and y=36

4x and x+25 are the dimensions

4(15)=30, and 15+25=40

P=2(30+40)

P=140

The ten sides of a regular decagon are colored with five different colors, so that all five colors are used, and sides that are
const2013 [10]

Answer:

  • <u>120</u>

Explanation:

Number the sides of the decagon: 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10, from top (currently red) clockwise.

  • The side number one can be colored of five different colors (red, orange, blue, green, or yellow): 5
  • The side number two can be colored with four different colors: 4
  • The side number three can be colored with three different colors: 3
  • The side number four can be colored with two different colors: 2
  • The side number five can be colored with the only color left: 1
  • Each of the sides six through ten can be colored with one color, the same as its opposite side: 1

Thus, by the multiplication or fundamental principle of counting, the number of different ways to color the decagon will be:

  • 5 × 4 × 3 × 2 ×1 × 1 × 1 × 1 × 1 × 1 = 120.

Notice that numbering the sides starting from other than the top side is a rotation of the decagon, which would lead to identical coloring decagons, not adding a new way to the number of ways to color the sides of the figure.

How do you solve 5 is _____ % of 25
Aneli [31]
Let the missing % be x.

Now, according to your question ;

5 = x% of  25

5 = x / 100 * 25

thus, 25x = 500

Thus, x = 500/25

= 20

Thus, 5 is 20% of 25.
