It is the transitive property. C It's actually a very good example of the transitive property.

The associative property would be (a + b) + c = a + (b + c) If you add a and b together and then add on c, that's the same thing as adding b + c together and then add a to it.

The Commutitive property would be a + b = b + a. Again it does not matter which entry you put into your calculator first.

The symmetry property is a = b or b = a. They are interchangeable. That's not what you are given.

The value of x is 3, while the length of the rectangle is 30 units and the width is 24 units.

<h3>How to determine the dimensions?</h3>

The given parameters are:

Base = 5(x+3)

Height = 2(x+9)

Perimeter = 108

The perimeter of a rectangle is

P = 2 *(Base + Height)

So, we have:

2 *(5(x + 3) + 2(x + 9)) = 108

Divide both sides by 2

5(x + 3) + 2(x + 9) = 54

Open the brackets

5x + 15 + 2x + 18 = 54

Evaluate the like terms

7x = 21

Divide by 7

x = 3

Substitute x = 3 in Base = 5(x+3) and Height = 2(x+9)

Base = 5(3+3) = 30

Height = 2(3+9) = 24

Hence, the value of x is 3, while the length of the rectangle is 30 units and the width is 24 units.

julio has 13 red marbles 4 blue mables and 8 yellow marbles julio draws a marble out of the bag 100 times how many time out of 1
Keith_Richards [23]

Answer:

16 times

Step-by-step explanation:

13 + 4 +8 = 25 total marbles

(4 is total number of blue marbles, 25 is complete total of marbles)

4/25 times =   ?/100 times

Because 25 times 4 is equal to 100, you then multiply 4 by 4 to get 16

16/100 times
