29 jars because if every box as 12 jars you multiply 12×29= 348
then multiply 29×16=$464
Answer:
19a+27b-54
Step-by-step explanation:
First distribute 7 into the first equation. (4a+3b-6) Multiply each coefficient and the constant by 7.
28a+21b-42
Then do the same for -3 and (3a-2b+4).
-9a+6b-12
Rewrite the equation 28a+21b-42-9a+6b-12.
Combine like terms: 19a+27b-54
So parcial products is 10(500)+10(70)+10(5)+4(500)+4(70)+4(5)=8050
Answer:
Truth value of ~(~p) is same as the truth value of p.
Step-by-step explanation:
For any statement p the truth table for p, ~p and ~(~p) will be as the figure attached. In this table we know that If truth value for p is true then ~p will be false and ~(~p) will be true which is same truth value as truth value of p.
Now if the truth value of any statement is false then truth value for ~p will be true and for ~(~p) will be false which is again similar to the statement p.
Hence truth value of any statement p is similar to the truth value of ~(~p).
