Which situation is represented by the equation? 6n + 12 = 2n + 36
Romashka [77]
<span>6n+12=2n+36
We move all terms to the left:
6n+12-(2n+36)=0
We get rid of parentheses
6n-2n-36+12=0
We add all the numbers together, and all the variables
4n-24=0
We move all terms containing n to the left, all other terms to the right
4n=24
n=24/4
n=6</span>

The spinner is divided into eight equal sections marked with eight different colors what situation could be represented by the s
meriva
I believe the answer you looking for is Probability.

This means that if someone spinned that wheel, they have a probability of getting the color they need.

For instance,
Let's say this wheel had the colors red, orange, yellow, green, blue, indigo, purple, and pink.
If I wanted the color red on the spinner, I have a 1/8 chance to spin the color red. I have a 7/8 chance of NOT spinning red. However, let's say the wheel had 4 colors that were pink and 4 colors that were blue. If I wanted to spin the color pink, I would have a 4/8 chance OF spinning it and a 4/8 chance of NOT spinning it. 4/8 is also equivilant to 1/2.

I hope this helps you understand!!
Please mark brainliest!!
Thanks!!
