Which of the following equations is an example of the Associative Property of Addition?

Choice B

(3+4) + 2 = 3 + (4+2)

Explanation:

The general rule for the associative property of addition is

(a+b)+c = a+(b+c)

the a,b,c stay in the same order from left to right. The only thing that changes is the way we group the pair of terms. On the left side, we have a & b together with c left out. Then on the right side, we have b & c together with 'a' excluded.

Addition of any group of numbers can be done in any order, which is why this property is valid (though perhaps there's a more rigorous proof out there). For this specific problem, a = 3, b = 4, and c = 2.

I think the answer to your question is option B.

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
