Answer:
x=-1
Step-by-step explanation:
4x-8=12x
4x=12+8
4x-12=8
-8x=8
-8x/-8= 8/-8
x=-1
The nth term for the given arithmetic sequence 45, 40, 35, 30 is 50 - 5n.
45, 40, 35, 30
The general formula for the nth term (an) of an arithmetic sequence is:
an = a1 + (n-1)d
where a1 is the first term and d is the common difference.
Plugging in the values from the given sequence, we can find the nth term:
an = 45 + (n-1)(-5)
Simplifying further, we get:
an = 50 - 5n
So, the nth term of the sequence is 50 - 5n.

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.
