Answer:

25x - 45 = 5(5x - 9)

Step-by-step explanation:

Find the greatest common factor (GCF) of 25 and 45.

You can do this several ways, but one way is to list all the factors of both numbers and find the greatest common one:

Factors of 25: 1, 5, 25

Factors of 45: 1, 3, 5, 9, 15, 45

Therefore, 25 and 45 have 2 common factors: 1 and 5

So the greatest common factors is 5

25x - 45 = 5(ax - b)

To find the value of a, simply divide 25 by 5: 25 ÷ 5 = 5

To find the value of b, divide 45 by 5: 45 ÷ 5 = 9

25x - 45 = 5(5x - 9)

Using the Fundamental Counting Theorem, we have that:

4. 1,757,600 different license plates can be there.

5. 676,000,000 different driver's license numbers can be formed.

<h3>What is the Fundamental Counting Theorem?</h3>

It is a theorem that states that if there are n things, each with n_1, n_2, \cdots, n_n ways to be done, each thing independent of the other, the number of ways they can be done is:

N = n_1 \times n_2 \times \cdots \times n_n

For the letters there are 26 outcomes and for the digits there are 10 outcomes, hence the parameters for item 4 are given as follows:

n_1 = n_2 = 26, n_3 = n_4 = 10, n_5 = 26

Hence the number of license plates is given by:

N = 26 x 26 x 10 x 10 x 26 = 1,757,600.

For item 5, the parameters are:

n_1 = n_2 = 26, n_3 = n_4 = n_5 = n_6 = n_7 = n_8 = 10

Hence the number of license numbers is:

26 x 26 x 10 x 10 x 10 x 10 x 10 x 10 = 676,000,000

LAST ONE GUYSSS \small \angle L and \small \angle M are supplementary, \small m\angle L=12x+45 and \small m\angle M=18x-30. Dete
svp [43]

Answer:

m\angle L = 111\degree \\m\angle M = 69\degree

Step-by-step explanation:

Since, angle L and angle M are supplementary.

\therefore m\angle L + m\angle M= 180\degree  \\ \therefore \: 12x + 45 + 18x - 30 = 180 \degree \\ \therefore \: 30x + 15= 180 \degree\\ \therefore \: 30x= 180 \degree - 15 \degree\\ \therefore \: 30x= 165 \degree  \\ x =  \frac{165 \degree}{30}  \\ x = 5.5 \degree \\  \\ m\angle L  = 12x + 45  \\ m\angle L = 12 \times 5.5 + 45 \\ m\angle L  = 66 + 45 \\ \huge \red{ \boxed{ m\angle L  = 111 \degree}} \\  \\ m\angle M=18x - 30 \\ m\angle M=18 \times 5.5 - 30 \\ m\angle M=99 - 30 \\ \huge \purple{ \boxed{ m\angle M=69 \degree}} \\

The corporate team building ecent will cost $6 if it has 3 attendees. if there are 8 attendees how much will the corporate team
zzz [600]

Answer:

<u>The team building event will cost $24 for 4 attendees.</u>

Step-by-step explanation:

Given,

Cost charged corporate team building = $6 for every attendee

Number of attendees = 4

We will multiply the amount of one ticket with number of attendees in order to find the total cost.

Cost charged for 4 attendees = 6*4

Cost charged for 4 attendees = $24
