This statement is false.
DeMorgan's laws are fundamental laws in propositional logic that show the relationship between negation, conjunction, and disjunction. Specifically, DeMorgan's laws state:
The negation of a conjunction is the disjunction of the negations: ¬(p ∧ q) ≡ ¬p ∨ ¬q
The negation of a disjunction is the conjunction of the negations: ¬(p ∨ q) ≡ ¬p ∧ ¬q
If the negation operator distributes over the conjunction and disjunction operators, then DeMorgan's laws are still valid. In fact, the distributive law of negation over conjunction and disjunction is sometimes called one of DeMorgan's laws. The distributive law states:
The negation of a conjunction is equivalent to the disjunction of the negations: ¬(p ∧ q) ≡ ¬p ∨ ¬q
The negation of a disjunction is equivalent to the conjunction negations: ¬(p ∨ q) ≡ ¬p ∧ ¬q
So, the distributive law of negation over conjunction and disjunction is a valid form of DeMorgan's laws.

Find the unknown angle
Answer:
A = 45°
Step-by-step explanation:
All angles in a triangle add up to 180°.
We know that one angle in the triangle is 90° (this is known because of the small square).
Hence:
A + A + 90° = 180°
Simplify
2A + 90° = 180°
Rearrange
2A = 180 - 90
2A = 90
Divide both sides by 2, so that A is by itself
A = 45°

Answer:
Complement of 50° = 40°
Supplement of 145° = 35°
Complement of 27° = 63°
Supplement of 50° = 130°
Step-by-step explanation:
Complementary angles add up to 90°
Supplementary angles add up to 180°
90° - 50° = 40°
180° - 145° = 35°
90° - 27° = 63°
180° - 50° = 130°
Answer:
Complement 50° = 40°
Supplement 145° = 35°
Complement 27° = 63°
Supplement 50° = 130°
Complement angles = adds up to 90°
Supplement angles = adds up to 180°

A local hamburger shop sold a combined total of 376 hamburger and cheeseburgers on Sunday. There were 74 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Sunday?
Answer:
82
Step-by-step explanation:
let X = the number of hamburgers sold
let Y = the number of cheeseburgers sold a combined total of 328 were sold
so: X + Y = 328
cheeseburgers = 3 times the number of hamburgers sold
so: Y = 3X
substitute 3X into the equation for Y
X + 3X = 328
4X = 328
divide both sides by 4 to get the variable X by itself
X = 82
so: 82 hamburgers were sold Friday
Answer:
There were 225 hamburgers sold on Sunday.
Step-by-step explanation:
2h - 74 = 376
h = hamburgers
2h - 74 + 74 = 376 + 74
2h = 450
2h/2 = 450/2
h = 225
Check.
hamburgers + cheeseburgers = total number of burgers
225 + (225 - 74)
225 + 151 = 376

A measure of how much space something takes up ?
Answer:
Volume
Step-by-step explanation:
Mass is measured using a scale. Volume is the amount of space matter takes up. Volume can be measured by multiplying the length, width, and height of an object, or by using a measuring cup and seeing how the measurement of water changes in a cup. Density is the amount of matter an object has in a certain space.

12x + 15y = 9
−12x − 18y = −6
HELP JUST SOLVE IT
Answer:
x = 2, y = -1
Step-by-step explanation:
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.
12x+15y=9,−12x−18y=−6
Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.
12x+15y=9
Subtract 15y from both sides of the equation.
12x=−15y+9
Divide both sides by 12.
x= 1/12 (−15y+9)
Multiply 1/12 times −15y+9.
x = -5/4y+3/4
Substitute -5y+3/4 for x in te other equation, -12x - 18y = -6
-12 ( -5/4y+3/4) -18y = -6
Multiply −12 times -5y +3/4
15y−9−18y=−6
Add 15y to −18y.
−3y−9=−6
Add 9 to both sides of the equation.
−3y=3
Divide both sides by −3.
y=−1
Substitute −1 for y in x= -5/4y+3/4. Because the resulting equation contains only one variable, you can solve for x directly.
x= -5/4(-1)+3/4
Multiply -5/4 times -1.
x = 5+3/4
Add 3/4 to 5/4 by finding a common denominator and adding the numerators. Then reduce the fraction to lowest terms if possible.
x=2
The system is solved.

Mang Nathaniel is selling two kinds of vinegar. Silver duck is priced at Php
10 per bottle and Reyna Puti is priced at Php 15 per bottle. If he needs a
total sales of Php 600.00, how many bottles of Reyna Puti should he sell if
there were already 30 bottles of Silver duck sold?
Answer:
Reyna Puti sold = 20 bottles
Step-by-step explanation:
Silver duck = Php 10 per bottle
Reyna Puti = Php 15 per bottle
Silver duck sold = 30 bottles
Reyna Puti sold = x bottles
Total sales = Php 600.00
Total = cost of Silver duck * number sold + cost of Reyna Puti * number sold
600 = 10 * 30 + 15 * x
600 = 300 + 15x
600 - 300 = 15x
300 = 15x
x = 300/15
x = 20 bottles
Reyna Puti sold = 20 bottles
