Hello!

To find the greatest common factor, you must find all the factors of both numbers and see which similar one is the greatest.

27: (1,27) (3,9)
36: (1,36) (2,18) (3,12) (4,9) (6,6)

As you can see the, the greatest common factor is 9.

I hope this helps!

Hello!

List the factors of each number

27 ⇒ 1, 3, 9, 27
36 ⇒ 1, 2, 3, 4, 6, 9, 12, 18, 36

The common factors are bold. The greatest common factor is 9

GCF ⇒ 9

Hope this helps! :)

Solve algebraically for x and explain each step( using mathematical vocbuary) for the following: 2(x+5)+ 3x = 30

Lelu [443]

First do distributive property
2x + 10 + 3x = 30
Now combine like terms
5x + 10 = 30
Subtract 10 from both sides
5x = 20
Divide both sides by 5
x = 4

Dawn and abed each roll a standard die obtaining a random number from 1 to 6. if the probability that dawns number is larger tha

larisa [96]

Answer:

a+b = 12

Step-by-step explanation:

There are 36 possible outcomes for rolling two dice. Let A be the number rolled by Abed and D be the number rolled by Dawn. The sample space, in the format [A,D], of all of the possibilities in which Dawn's number is larger is:

[5,6]

[4,5] [4,6]

[3.4] [3,5] [3.6]

[2,3] [2.4] [2,5] [2.6]

[1,2] [1,3] [1.4] [1,5] [1.6]

There are 15 ways out of 36 possible ways of Dawn getting the higher number. In the simplest form:

$\frac{15}{36}=\frac{5}{12}=\frac{a}{b}\\ a+b = 5+12 = 17$
