The difference of twice a number and 4 is 16 .
german

Answer:

Let X be the number.

Twice the number would be 2x

The difference between the two, would be subtraction, so you would subtract 4 from 2x


The equation becomes 2x-4 = 16


Now solve for x:

2x-4 = 16

Add 4 to each side:

2x = 20

Divide both sides by 2:

x = 20/2

x = 10


The number is 10.

Find the greatest common factor of each set of numbers 24 40 and 56
Artemon [7]

To get the greatest common factor of a list of numbers, you can use a neat trick.

First, get the greatest common factor of the first two. Then, the greatest common factor of that and the third, and so on.

In this case, we need to get the greatest common factor of 24 and 40.

I'll use Euclid's algorithm (you can look that up in google, it's just a nice way to find the GCF of two numbers)

24, 40

40, 24

24, 16

16, 8

8, 0

So we get 8. Now we need to get the greatest common factor of 8 and 56:

8, 56

56, 8

8, 0

We get 8 again, and that is the greatest common factor of the three numbers.

Hope this helps :)
