The "product" of two numbers means you multiply them.
So, you are multiplying (8-n), where n = "a number," by 7.
Then, when you decrease (subtract) this product by 5, you get 40.
So the whole thing looks like
7(8-n) - 5 = 40.

Answer:
The provided statement is not a binomial experiment.
Step-by-step explanation:
Four conditions of a binomial experiment:
There should be fixed number of trials
Each trial is independent with respect to the others
The maximum possible outcomes are two
The probability of each outcome remains constant.
For example:
Binomial distribution: Asking 200 people if they ever visit to new york.
Not Binomial distribution: Asking 200 people how much they earn in a week.
Now, observe the provided information:
We need to determine that, asking 100 people which brand of car they drive is a binomial experiment or not.
Clearly it is not a binomial experiment because the maximum possible outcomes are not two.
Therefore, the provided statement is not a binomial experiment.

Answer: Choice B</h3>
==========================================
Explanation:
Here's a slightly more detailed breakdown of what's going on
3x + 2y = 15 ... start with the first equation
3x + 2( y ) = 15 .... the parenthesis don't change the expression
3x + 2( 3x+5) = 15 ... replace y with 3x+5; since y = 3x+5
From here, you solve for x like you would any other single variable equation. Once you know x, you can determine y through y = 3x+5.
