If the order matters, then there are 8P3 = 8! / (8 - 3)! = 8! / 5! = 8 x 7 x 6 = 336 ways to present the ribbons.
The solution to the equation is x = 4
<h3>What are linear equations?</h3>
Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
<h3>How to determine the solution to the system?</h3>
A system of linear equations is a collection of at least two linear equations.
In this case, the equation is given as
(x + 20)/2 = 3x
Multiply both sides of the equation by 2
x + 20 = 6x
Subtract x from both sides of the equation
5x = 20
Divide both sides of the equation by 5
x = 4
hence, the solution to the equation is x = 4

Answer:
x=6
y=-3
Step-by-step explanation:
<em><u>solve for x-</u></em>
-4x+8y=-24 replace y with 0
-4x+8(0)=-24
-4x=-24 divide by -4 on both sides
x=6
<u><em>Solve for y-</em></u>
-4x+8y=-24 replace x with 0
-4(0)+8y=-24
8y=-24 divide by 8 from both sides
y=-3
Hello!
To find the mean you add all the numbers and divide the sum by the amount of numbers added
14 + 19 + 18 + 12 + 22 + 15 + 16 + 16 + 14 + 14 + 21 + 20 = 201
Divide the sum by the amount of numbers added
201 / 12 = 16.75
The answer is C) 16.75
Hope this helps!
