If s is true and j is false, is the following true or false (~s v j) ^ (s v~ j)
nexus9112 [7]
S = true
~s = false
-------------
j = false
~j = true
-------------
~s = false and j = false, so,
~s v j = (false) v (false)
~s v j = false
-------------
Similarly,
s v ~j = (true) v (true)
s v ~j = true
-------------
We have 
~s v j = false
and 
s v ~j = true
which lead to this when we conjunct the two logical expressions
(~s v j) ^ (s v ~j) = (false) ^ (true)
(~s v j) ^ (s v ~j) = false
-------------
-------------
The final answer is false

Solve the equation 3(x+4.5x ) = 36. Explain your reasoning THOROUGHLY.
Vesna [10]

Answer:

x \approx 2.18

Step-by-step explanation:

3(x+4.5x)=36

we can use the distributive property and get

3(x)+3(4.5x)=36\\\\3x+13.5x=36\\\\

and we can add like terms

(3+13.5)x=36\\\\16.5x=36

and know we divide both sides by 16.5

16.5x*(\frac{1}{16.5})=36*(\frac{1}{16.5})\\\\x=\frac{36}{16.5}

and doing the dvision we get that

x\approx 2.18
