Answer:

The competition took 12.5 minutes.

Step-by-step explanation:

Let the time taken by Achilles to complete the competition is h hours.

Now, Achilles runs at a speed of 13 mph while the Turtle moves at a speed of 1 mph.

So, the competition was 13h miles long.

Now, Turtle will take h hours to complete h miles of the competition.

Now, given that (13h - h) = 2.5

⇒ 12h = 2.5

⇒ h = 0.208 hours.

⇒ h = 12.5 minutes.

Therefore, the competition took 12.5 minutes. (Answer)

Which classification describes the following system of equations? inconsistent and dependent consistent and dependent consistent
sveta [45]

The system of equations is consistent and independent and the solutions are x = 4, y = 5, and z = -1 option third is correct.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have three linear equations in three variables:

x - y - z = 0 ..(1)

2x - y + 2z = 1 ..(2)

x - y + z = -2 ..(3)

From the equation (1):

\rm x=y+z

Plug this value in the equation (2) and (3):

\rm 2\left(y+z\right)-y+2z=1\\\\ y+z-y+z=-2

After solving we get:

z = -1

y = 5

Plug the above two values in equation (1) we get:

x = 4

Thus, the system of equations is consistent and independent and the solutions are x = 4, y = 5, and z = -1 option third is correct.

What is the GCF of two prime numbers?
ehidna [41]
Prime numbers: numbers which only have the factors of themselves and 1.

They include numbers such as 17, 19, 23, etc. These are numbers which only have two factors: such as 17, with the factors only being 17 and 1.

So therefore, this means, that for any two prime numbers, unless they are the same number, the only factor they will share is 1. So therefore the GCF of two prime numbers is 1.

Hope this helped!
