Answer:

The GCF or greatest common factor of 12w and 15wz would be 3w

Step-by-step explanation:

The coefficients 15 and 12 without variables have the factor 3 in common and no others than themselves and 1. After finding 3 is the starting factor, next is to look at the variable after the coefficients which are wz and w. Since both 12w and 15wz only share w, lt will then be 3w as the greatest factor.

Hope this helps!

Using principle of mathematical induction prove that 6^-1 divisble by 5 .

salantis [7]

I suppose the claim is $5 \mid 6^n - 1$ for $n\in\Bbb N$ .

When $n=1$ , we have $6^1 - 1 = 6 - 1 = 5$ , and of course 5 divides 5.

Assume the claim holds for $n=k$ , that $5 \mid 6^k - 1$ . We want to use this to show it holds for $n=k+1$ , that $5 \mid 6^{k+1} - 1$ .

We have

$6^{k+1} - 1 = \left(6^{k+1} - 6\right) + \left(6 - 1) = 6\left(6^k - 1\right) + 5$

Since $5 \mid 6^k - 1$ , we can write $6^k - 1 = 5\ell$ for some integer $\ell$ . Then

$6^{k+1} - 1 = 6\cdot5\ell + 5 = 5(6\ell + 1)$

which is clearly divisible by 5. QED

What is the reciprocal of each mixed number? Drag and drop the answer into the box to match each number.

Gnoma [55]

Hi there!!

First, we are going to find the improper fraction of each mixed number.

10 1/3 >>>>> 10*3+1=31 31/3

2 2/3 >>>>> 2*3+2=8. 8/3

5 1/3 >>>>>> 5*3+1 = 16. 16/3

TO find the reciprocal, we switch the numerator with the denominator.

31/3 changes to 3/31, 8/3 changes to 3/8, and finally 16/3 changes to 3/16.

Your answer is:

3/31
3/8
3/16

Hope this helps! Let me know if you have any questions:)
