I'll interpret the given statement as
where 
means "not <em>x</em>", 
means "or", and 
means "and".
If <em>r</em> is false, then 
is true.
<em>s</em> is given to be false, so 
(basically "true and false") is false.
If <em>s</em> is false, then 
is true.
Then 
(i.e. "true or false") is true.
Take the negation of that and you end up with a false statement.
If you intended "~r < s" to mean something like "not r is implied by s", so the original statement is actually
then 
is true because <em>s</em> is false. Then 
is still true, so the statement still ends up being false.
A. coffee and soda consumes (55%+65)-100%=120%-100%=20%
P1=20/100=2/10=1/5
b. does not consume at least one of these products= 100-75=25 %
P2= 25/100=1/4
The answer is C. x, in the first equation. The first equation is easiest to simplify since other than 8y is their common variable, equation 1 is also divisible by 2 so it will not contain any fractions which would be harder to simplify.
Rearranging the first equation, the result would be:
2x + 8y = 12
8y = 12-2x----equation 1
This equation can then be directly substituted to the second equation since the value of 8y is given.
Substitute the right hand of the first equation of 8y which is 12-2x to the second equation. The result would be:
3x-(12-2x) = 11
3x-12 + 2x =11
5x = 11+12
5x = 23
x= 23/5
Answer:
(2 + 3) + 6 - 2
Step-by-step explanation:
(2 + 3) + 6 - 2
2 + 3 = 5
5 + 6 = 11
11 - 2 = 9
= 9
