Answer:
or 
Step-by-step explanation:
Substitution means plugging in one variable's value that consists of the opposite variable. Because 
is already specified, you can plug it into the second equation's 
value. After doing that, it looks like this:
Then you would distribute the 
across the parentheses next to it, like this:
Then, add like terms, like this:
Then divide both side by 
to isolate 
.
Now, you can plug 
() into either equation, but the first one seems simpler so you would pick that. It would look like this:
Solving would look like this:
So the answer is or .
Answer: They show numerical value. You have to make them clear.
Step-by-step explanation:
Answer:
hello : 6.23x10^14 > 8.912x10^12^12
Step-by-step explanation:
let : A= 6.23x10^14 and B = 8.912x10^12
A= (6.23x10^2) x10^12 ... because : 10^14 = 10^2x10^12
A = 623 x 10^12
623 > 8.912
so : A > B
prob( it lands on open end) = 8/20 = 2/5
prob ( lands on closed end) = 4/20 = 1/5
The second choice is correct.
Every mixed number is (a whole number) + (a piece of another one).
So every mixed number must be bigger than ' 1 ', because ' 1 ' is the
smallest whole number.
77/200 is less than ' 1 ', because the numerator is less than the
denominator. So it doesn't have what it takes to be a whole number.
Every fraction is a short way to write a division problem. It means
(the top number) divided by (the bottom number).
When you actually do the division, the answer is the decimal form
of the fraction.
When you divide 77 by 200 , you get 0.385 .
