Kim finds a 1-meter tree branch and marks it off in thirds and fifths. She then breaks the branch along all the markings and rem

True [87]

Answer:

3/5

Step-by-step explanation:

We want to find the fraction of the original branch that remains, so we will assume a length of the branch in order to make our calculation easier.

Since Kim marks it off in thirds and fifths, let's find the least common multiple of 3 & 5.

Least common multiple of 3 & 5 is 15.

Thus,let's make the length of the branch to be 15-meter long.

Now, if the branch is 15 m long, considering the markings of thirds and fifths, the branch would be cut at:

3, 5, 6, 9, 10, 12 meters.

We are told that She then breaks the branch along all the markings and removes one piece of every distinct length. Thus;

Distinct lengths are;

3 metres

5 - 3 = 2 metres

10 - 9 = 1 meter

Total she removes = 3 + 2 + 1 = 6 meters.

Total remaining is;

15 - 6 = 9 meters

Expressing this as a fraction of the original branch gives:

9/15

Divide both numerator and denominator by 3 to get; 3/5

What is the solution to the system of equations?

Over [174]

ANSWER

C) (6,-8)

EXPLANATION

The equations are:

$y = \frac{1}{3}x - 10$

and

$2x+y=4$

We substitute the first equation into the second equation to get:

$2x + \frac{1}{3}x - 10 = 4$

We multiply through by 3 to get:

$6x + x - 30= 12$

Group similar terms,

$6x + x = 30 + 12$

$7x = 42$

Divide both sides by 7 to get,

$x = \frac{42}{7} = 6$

Put this value of x into the first equation to get;

$y = \frac{1}{3} (6) - 10$

$y = 2 - 10 = - 8$

Which table represents y as a function of x?

dezoksy [38]

Answer:

1 is the answer see attached

Step-by-step explanation:

1 is a function

2 is not a function as it is x+y

3 is a boundary function of how many parameters

4 is not a function as such parameters are too long however many of the decimals divide into each other and appear functional.
