expeople1 [14]

Answer: dependent events

Step-by-step explanation:

Dependent events are refered to as the events that occur when occurrence of one of the events has an effect on the chances of the other event occuring as well.

8x + 2 – 6 = 4x +8 +3x
Viefleur [7K]
The first step is to combine like terms. So u would do 2-6. You then get -4 then u just bring everything else down. So now u should have this :

8x -4 = 4x + 8 + 3x

Now you do the same thing to the other side. U combine like terms which in this case are 4x and 3x. So u just do 4+3 which is 7 so now u have 7x. So now ur equation would be:

8x -4 = 7x +8

Now u do the inverse of 7 which would be -7 and u do that on both sides. So it would look like this :

8x -4 = 7x + 8
-7x. -7x

So now 7 and -7 cancel each other other and 8 -7 is 1 so now u have one x. So ur equation would now look like this:

1x -4 = 8

Now u do the inverse of negative 4 which is +4. So you would add 4 on both sides on both sides. Like shown:

1x -4 = 8
+4 +4

So u just add 8 + 4 which is 12. Now since anything times 1 is itself ur answer will be X=12


Hope this helped

What is the simplified form of the equation 4/5n - 1/5 = 2/5n ?
Gnoma [55]

we are given

\frac{4}{5}n -\frac{1}{5} =\frac{2}{5}n

Firstly , we will multiply both sides by 5

5*\frac{4}{5}n -5*\frac{1}{5} =5*\frac{2}{5}n

now, we can simplify it

4n-1 =2n

2n =1

now, we can solve for n

n =\frac{1}{2}.............Answer
