Twice the difference of a number and six is the same as twelve . Write into algebraic equation

Mathematics
1 answer:
DiKsa [7]3 years ago

Answer:

2(n-6)=12

(I went too far in my explanation; I'm not going to erase it because I think it is important to have an example on solving these)

Step-by-step explanation:

Twice the difference of a number and 6 is the same as 12.

Twice means 2 times

Difference means the result of subtracting something.

is the same as means equal to (=).

So we are given 2(n-6)=12.

You can start by dividing 2 on both sides are distributing 2 to terms in the ( ).

I will do it both ways and you can pick your favorite.

2(n-6)=12

Divide both sides by 2.

 n-6  =6

Add 6 on both sides

 n     =12

OR!

2(n-6)=12

Distribute 2 to both terms in the ( )

2n-12=12

Add 12 on both sides

2n    =24

Divide both sides by 2

n       =12

How to solve graph 5+h>7
bogdanovich [222]

Answer:

h > 2

Step-by-step explanation:

It may look hard, but it is not really.

1. Solve

Here we have the equation 5+h>7.

All we have to do to find h is to subtract 5 from both sides.

5+h>7

-5     -5

When you subtract 5 from both sides, you get

5 - 5 = 0

7 - 5 = 2

All is left is 0+h>2, or h > 2.

2. Substitute

To make sure, (I do this but you can if you want to) I will substitute.

The values of <u><em>h </em></u> have to be greater than 2. So, Let's substitute 3.

5 + h > 7 --> 5 + 3 > 7

It's simple math.

5+3=8

8>7

Now, also to confirm, let's try a value less than 2, 1.

5 + h > 7

5 + 1 > 7

6 > 7 is not true, so it is confirmed that anything less than 2 is not true and anything greater is true.

Hence, h > 2
