Good evening ,
______
Answer:
12×11×10×9×8×7= 665 280 ways
___________________
Step-by-step explanation:
The first inquiry has 12 ways
The 2nd inquiry has 11 ways
The 3rd inquiry has 10 ways
The 4th inquiry has 9 ways
The 5th inquiry has 8 ways
The 6th inquiry has 7 ways
Answer:
length = 11 yard
width = 5 yard
Step-by-step explanation:
Area of a rectangle = L W
where A = 55 yard
L = 3W - 4
find: Length
width
solution:
A = L W
55 = (3W - 4) W
55 = 3W² - 4W
3W² - 4W - 55 = 0
use quadratic equation to solve for W:
W = <u> - (-4) ± √(-4)² - 4(3)-55 </u>
2(3)
W = 5, W = -11/3
substitute W=5 to equation L = 3W - 4 to solve for L
L = 3W - 4
L = 3(5) - 4
L = 15 - 4
L = 11
therefore, the dimensions of a rectangle:
length = 11 yard
width = 5 yard
For this case we have the following system of equations:
To solve, we clear "x" from the second equation:
We substitute "x" in the first equation:
We clear the value of the variable "y":
We look for the value of the variable "x":
Thus, the solution of the system is given by:
Answer:
Option D
Answer: x = 3
Step-by-step explanation:
-5 -x = -8
-× = -8 + 5
-x = -3
x = 3
Example of six ordered pairs with country names alongside their capitals are:
{(England, London), (USA, Washington DC), (India, New Delhi), (Nepal, Kathmandu), (Austria, Vienna), (Albania, Tirana)}.
<h3>What are Ordered Pairs?</h3>
- Ordered pair can be described as a pair of objects or numbers in a particular order.
- In an ordered pair, the order of the objects or numbers are very important. For example, (a, b) is not the same as (b, a).
Therefore, example of six ordered pairs with country names alongside their capitals are:
{(England, London), (USA, Washington DC), (India, New Delhi), (Nepal, Kathmandu), (Austria, Vienna), (Albania, Tirana)}.
