The Least Common Multiple or (LCM) of 9 and 3 is 9

When we are talking about Least Common Multiple, we are thinking of the smallest number that is a multiple of both numbers. So, I am going to give us the first 4 multiples of each of the numbers given to us:

3:
-3
-6
-9
-12

9:
-9
-18
-27
-36

Now these are the first 4 multiples of both of the numbers given to us. If we look, there is a match for the LCM, which is 9. That means 9 is the LCM of 9 and 3.

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you any further! :D

Hailey sold 20 tickets to the school play for a total of 225$.Early bird tickets were 10$ and regular priced tickets were 15$.Wr

dlinn [17]

Answer:

The system of equation are $\left \{ x+y=20} \atop {10x+15y=225}} \right.$

The number of early bird tickets are 15 and of regular tickets are 5.

Step-by-step explanation:

Given,

Total number of tickets = 20

Total amount = $225

Solution,

Let the number of early bird tickets be 'x'.

And also let the number of regular tickets be 'y'.

Now total number of tickets is the sum of number of early bird tickets and number of regular tickets.

So framing in equation form, we get;

Total number of tickets = number of early bird tickets + number of regular tickets

$x+y=20\ \ \ \ equation\ 1$

Again, Total amount is the sum of number of early bird tickets multiplied with price of each ticket and number of regular tickets multiplied with price of each ticket.

So framing in equation form, we get;

$10x+15y=225\ \ \ \ \ equation\ 2$

Hence the system of equation are $\left \{ x+y=20} \atop {10x+15y=225}} \right.$

Now we solve the equation by multiplying equation 1 by 10, and get;

$10(x+y)=20\times10\\\\10x+10y=200\ \ \ \ equation\ 3$

Now subtracting equation 3 from equation 2, we get;

$(10x+15y)-(10x+10y)=225-200\\\\10x+15y-10x-10y=25\\\\5y=25\\\\y=\frac{25}{5}=5$

On substituting the value of 'y' in equation 1, we get;

$x+y=20\\\\x+5=20\\\\x=20-5=15$

Hence The number of early bird tickets are 15 and of regular tickets are 5.

A rectangular garden has a length that is

skelet666 [1.2K]

Answer:

Since,

Length is 4 times Breadth

Let Breadth be x

Therefore,Length=4x

Perimeter=50m

Therefore,

50m=2(l+b)

50m=2(4x+x)

50m=2(5x)

50m=10x

x=5m.

Therefore,

Breadth=5m

Length=4x=4×5=20m

Use the inverse variation equation to fill in the table.

Mandarinka [93]

The value of a is 0.10.

The value of b is 20.78.

The value of c is 0.02.

<h3>What are the missing values?</h3>

When two variables have inverse variation, the two variables move in opposite directions. If one variable increases, the other decreases.

p = 8.31 / V

V = 8.31 / p

a = 8.31 / 83.1 = 0.10

b = 8.31 / 0.4 = 20.78

c = 8.31 / 415.5 = 0.02
