There are actually 2 variations in this case.

> First case: the number of sides is an odd number

<span>                The number of lines of symmetry is simply equal to number of sides</span>

 

> Second case: the number of sides is an even number

<span>                The number of lines of symmetry is equal to twice the number of sides</span>

X sides because every regular polygon has the same amount of lines of symmetry as the amount of sides.

Marina86 [1]

Answer:

6 1/10

Step-by-step explanation:

Convert the mixed numbers into improper fractions (denominator × whole number + numerator / denominator):

9 2/5 = 47/5

3 3/10 = 33/10

Convert improper fractions to have the same denominator:

47/5 × 2/2 = 94/10

Find the difference by subtracting the numerators:

94/10 - 33/10 = 61/10

Convert the answer into a mixed number:

61/10 = 6 1/10

What is 4 over 15 plus negative 7 over 45
IgorLugansk [536]

Answer:

If what I think youre saying is correct, then it should be 1/9

Step-by-step explanation:

4/15 + (-7/45)

Multiply both numerator and denominator of 4/15 by 3 so that the denominator becomes 45 to match the other fraction.

12/45 + (-7/45)

As the fraction on the right side is negative, it is taken away from the left fraction, hence:

(12 - 7)/45

Therefore, with simple subtraction,

5/45

Simplify to 1/9

katrin [286]

The solution set for the given inequality is g > -7

<u>Given the following inequality:</u>

  • 4 - 5g > 39

<h3>What is an inequality?</h3>

An inequality can be defined as a mathematical relation that is typically used to compare two (2) integers or variables in an equation by illustrating any of the following:

  • Greater than (>).
  • Less than (<).
  • Greater than or equal to the other (≥).
  • Less than or equal to the other (≤).

Simplifying the inequality, we have:

4 - 5g > 39\\\\5g > 4-39\\\\5g > -35\\\\g > -7
