Answer is C= 52d
To solve problems like this, you would just need to think about what the question is asking you one step at a time
List what you know
- There are 52 cards in each deck
- We need how many cards in total
So let us think about it from a mathematical standpoint
1 deck= 52 cards 1 x 52= 52
that means.....
2 deck= 104 cards 2 x 52 = 104
3 deck= 158 cards 3 x 52 = 158
and the list keeps going
That means that 52 multiplied by whatever number d is will get you the total number of cards.
thus C= 52d

Subtraction 9 minus 36 is -27
Your answer is -27
Answer:
1. 3x + 2
2. 0.25x - 6.5
3. $5.50 per sandwich
Step-by-step explanation:
1.
6x + 1 - (3x - 1)
PEMDAS says solve everything in the parentheses first
There is nothing left to simplify within the parentheses.
Since there's also no exponents, multiplication, or division, let's combine like terms starting from left to right
6x - 3x + 1 + 1
Negative + Negative = Positive, hence why it became 1 + 1
3x + 2
2.
(3x - 1) - 2.75 (x + 2)
PEMDAS says to do multiplication next (since parentheses are fully simplified and there are no exponents)
(3x - 1) - 2.75x - 5.5
Negative + Positive = Negative, hence why it became -5.5
3x - 1 - 2.75x - 5.5
Combine like terms
3x - 2.75x - 1 - 5.5
0.25x - 6.5
3.
Set up an equation:
Variable x = cost of sandwiches
4x + 4(2) = 30
4x + 8 = 30
Subtract 8 from both sides to isolate the variable
4x + 8 - 8 = 30 - 8
4x = 22
Divide both sides by 4
4x ÷ 4 = 22 ÷ 4
x = 5.5

Answer: x = 18
Step-by-step explanation:
<span>The size of a RAM for a computer is 256M words, where each word is 16 bits long is 256M *16.
So the capacity is,
=256M*16bits
=256*2^20*16bits
=2^32 bits
=4294967296 bits.</span>
