The expression for the total number of cards in n deck of cards is 52n.
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of decks of cards = n
Number of cards in a deck = 52
Now,
The number of cards in n deck of cards.
= 52 x n
= 52n
Thus,
The number of cards is 52n.

Answer:
2160 eggs on Monday
Step-by-step explanation:
Jim keeps 12 hens in every coop but Jim has 20 coops
12x20=240 hens
Every hen lays 9 eggs = 12x9= 108 eggs for 1 coop
108x20 = 2160 for 20 coops on Monday

The requried line is not parallel to the graph of y = 9x + 1 is 1. 9y - x = 2. Option A is correct.
To determine which line is not parallel to the graph of y = 9x + 1, we need to compare the slopes of each line to the slope of y = 9x + 1.
The equation y = mx + b represents a line with slope m. In the case of y = 9x + 1, the slope (m) is 9.
Now, let's check the slopes of each equation given:
A. 9y - x = 2:
To write this equation in the form y = mx + b, we rearrange it as y = (1/9)x + 2/9. The slope is (1/9), which is not equal to 9. Therefore, this line is not parallel to y = 9x + 1.
B. y - 9x = 3:
Rearranging this equation as y = 9x + 3, we can see that the slope is 9, which is equal to the slope of y = 9x + 1. Therefore, this line is parallel to y = 9x + 1.
C. 9x - y = 2:
Rewriting this equation in the form y = mx + b, we get y = 9x - 2. The slope is 9, which is equal to the slope of y = 9x + 1. Therefore, this line is parallel to y = 9x + 1.
D. 27x - 3y = 2:
To put this equation in the form y = mx + b, we divide both sides by 3, which gives 9x - y = 2/3. The slope is 9, which is equal to the slope of y = 9x + 1. Therefore, this line is also parallel to y = 9x + 1.
In summary, the line not parallel to the graph of y = 9x + 1 is 1. 9y - x = 2. Option A is correct.
