Answer:
D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.
Step-by-step explanation:
Associative Property of Addition states that for any groups of numbers, the order of addition does not matter.
or, for any numbers A, B and C
A + ( B +C) = (A +B) + C
Here, D. (3 + 4) + 9 = 3 + (4 +9) represents the Associative Property of Addition.
Answer:
y = 2x - 12
Step-by-step explanation:
To find the inverse of a function, you switch x and y and solve for y.
x = 1/2 y + 6 switch x and y
x - 6 = 1/2 y subtract 6 from both sides
2x - 12 = y multiply both sides by 2

Answer: B) Linear pair postulate</h3>
Explanation:
As the name implies, "linear pair" means the two angles combine to form a straight line of 180 degrees. Think of gluing the angles together.
As an example, let's say angle 1 was 50 degrees and angle 4 is 130 degrees. They combine to 50+130 = 180 which is a straight angle. I recommend using a protractor to help draw these angles.
Let the number of hamburgers sold be "h" and the number of cheeseburgers be "2h" as it was two time as the humbugers .form equation frome it '2h+h=387".comp the like terms which gives you 3h=387 divide each side by 3 which gives you h=129 which is equal to the number hambyrgers .multiply 129 by 2 to get the number of cheeseburgers which is 258
Answer is D.) 48π ft²
Given:
3 circular rugs.
radius: 4 ft
Area of a circle = π r²
A = 3.14 * (4ft)²
A = 3.14 * 16ft²
A = 50.24 ft²
Total area of 3 rugs
50.24 ft² * 3 rugs = 150.72 ft²
Equation leaving π.
150.72ft² ÷ 3.14 = 48ft²
D.) 48π ft²
