The linear equation for the given situation is represented as:
20x + 12y = 1,300
correct answer option: b
<h3>What is a linear equation with two variables?</h3>A general linear equation in two variables is defined as an equation of the form ax + by + c = 0, where x and y are the two variables and a, b, and c are real numbers and a and b are non-zero (x and y).
Given:
We use variables to represent the cost of the big and the smaller boxes.
According to the question, let x be the selling price of the big boxes.
The selling price of the bigger boxes is y.
The total selling price of the smaller boxes is 20x.
The total selling price of the bigger ones is 12y.
Now we know he is making a profit of $1,300 on the total transaction.
Hence the linear equation in two variables for the given situation is represented as:
20x + 12y = 1,300

I understand that the question you are looking for is:
Jackson sells two types of toolboxes. he plans on selling them during a farming fair this weekend. He estimates he will sell 20 of the smaller boxes (X) and 12 of the larger boxes (Y). if he'd like the profit to be $1300, which of the following best displays the equation that represents this information?
A- y+12=20(x-1300)
B- y=- x+
C- 20x+12y=1300
D- 12y=20x-1300
Answer:
0.64 = 64% probability that the student passes both subjects.
0.86 = 86% probability that the student passes at least one of the two subjects
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Passing subject A
Event B: Passing subject B
The probability of passing subject A is 0.8.
This means that
If you have passed subject A, the probability of passing subject B is 0.8.
This means that
Find the probability that the student passes both subjects?
This is . So
0.64 = 64% probability that the student passes both subjects.
Find the probability that the student passes at least one of the two subjects
This is:
Considering , we have that:
0.86 = 86% probability that the student passes at least one of the two subjects
