Answer:

2. Since it is equilateral, we just set up an equation with using any two sides (since they are all equal)

12x - 22 = 10x - 6

12x - 10x - 22 = -6

2x - 22 = -6

2x = 22 - 6

2x = 16

x = 16/2

x = 8

Each side = 74

3. Same formula for this. Get any two sides and setup the equation.

4x - 25 = x + 14

4x - x - 25 = 14

3x = 25 + 14

3x = 39

x = 39/3

x = 13

Each side = 27

4. This one is also simple. Since DE = EF. We substitute its sides with the equations.

8x - 13 = 5x + 17

8x - 5x - 13 = 17

3x - 13 = 17

3x = 17 + 13

3x = 30

x = 30/3

x = 10

DE and EF = 67

DF = 31

You are converting 8 centimeters to meters. How will the<br> number of meters compare to 8? Explain.
Anton [14]

Answer:

  the number of meters is smaller than 8

Step-by-step explanation:

A meter is 100 times the length of a centimeter, so it takes a factor of 100 fewer of them to have the same length.

  8 cm = 0.08 m

0.08 is a smaller number than 8. The number of meters is less than the number of centimeters (by a factor of 100).
