You asked
8 divided by 3 plus 6=
(8/3) + 6 = 2(2/3) + 6 or
8/3 + 18/3 = ??/3

I don't understand how to describe pairs of related variables what's the difference between dependent & independent variables

I'm not what class your question is arising from. If this is a math question then the independent variable is the one the one who's change is being observed. The dependent variable is calculated from the independent variable. If e.g. you look at the equation for a line, the x coordinate is usually the one we're thinking of as the independent variable and the y coordinate is the dependent variable.
If you question is coming from a natural or behavorial science course then different terminology and explanations might apply.

your dependent is the y value and the independet is the x value

To determine the answer for the expression, 8 divided by 3 plus 6, we need to follow the order of operations (also known as PEMDAS or BIDMAS). This involves performing any calculations within parentheses or brackets first, then evaluating any exponents or roots, followed by any multiplication or division, and finally any addition or subtraction.

In this case, there are no parentheses or exponents, so we move on to multiplication and division. We divide 8 by 3, which gives us a quotient of approximately 2.67.

Now, we move on to addition. We add the result of the division, 2.67, to 6.

So, 8 divided by 3 plus 6 equals 8.67 (rounded to two decimal places).
