Total thickness of the stack of cards = 3/4 inch or 0.75 inch
In a full stack of cards, there are 52 cards.
Hence, the thickness of 52 cards = 0.75 inch.
To find the thickness of one card, we divide the total thickness with the total number of cards.
Thickness of one card = 
1 inch = 2.54 cm
0.014423 inch is approximately equal to 0.34 cm.
Answer = 0.34 cm
You can make some algebraic equations and solve it.
The first would be:
The second would be
You can then rearrange the second into
And subsitute it into the first like so:
After that, distribute the y into the parantheses.
Subtract the 21 on both sides and multiply by -1 on both sides:
You then can factor it into:
With Zero Product Property, we can determine y to be either -3 and 7. Since the variables are interchangable, you can say the same about x, just that whatever x is, y must be the other value.
Thus, the answer is 7 and -3.
Answer:
x = 77 ft
Step-by-step explanation:
55 ÷ 45 = 1.222222222
1.222222222 x 63 = 77
Answer:
10=y/11-13
We move all terms to the left:
-10-(y/11-13)=0
-y/11+13-10=0
We multiply all the terms by the denominator
-y+13*11-10*11=0
We add all the numbers together, and all the variables
-1y+33=0
We move all terms containing y to the left, all other terms to the right
-y=-33
y=-33/-1
y=+33
