To get the Greates Common Factor (GCF) of 15 and 36 we need to factor each value first and then we choose all the copies of factors and multiply them:  

15:        3   5

36:    2 2 3 3  

GCF:        3    

The Greates Common Factor (GCF) is:   3

6x - 3y = -6<br> y = 2x + 2
Verizon [17]

Answer:

y=0, x=1

Step-by-step explanation:

6x-3y= -6 ...... equation 1

y =2x+2 ..... equation 2

subtract 2x from both sides

y-2x=2x-2x+2

y-2x=2

6x-3y= -6

y-2x=2

Rearrange

6x-3y= -6 ........x1

-2x +y=2............x3

6x-3y= -6

-6x +3y=2

0y=0

y=0

substitute y=0 in equation 1

6x-3xo= -6

6x= -6

x-6/6

x = -1

Prove: If n is a positiveinteger and n2 is<br> divisible by 3, then n is divisible by3.
notka56 [123]

Answer:

If n^2 is divisible by 3, the n is also divisible by 3.

Step-by-step explanation:

We will prove this with the help of contrapositive that is we prove that if n is not divisible by 3, then, n^2 is not divisible by 3.

Let n not be divisible by 3. Then \frac{n}{3} can be written in the form of fraction \frac{x}{y}, where x and y are co-prime to each other or in other words the fraction is in lowest form.

Now, squaring

\frac{n^2}{9} = \frac{x^2}{y^2}

Thus,

n^2 = \frac{9x^2}{y^2}

\frac{n^2}{3} = \frac{3x^2}{y^2}

It can be clearly seen that the fraction \frac{3x^2}{y^2} is in lowest form.

Hence, n^2 is not divisible by 3.

Thus, by contrapositivity if n^2 is divisible by 3, the n is also divisible by 3.
