Which property is used in the statement? if y = 3 and 3 = 2 + 1, then y = 2 + 1.
transitive property
symmetric property
addition property of equality
subtraction property of equality

The correct answer is "C" (Addition property of equality)

Step-by-step explanation:

1. Are the two expression equal in anyway to each other?

2. When adding a value for example as show in the question "y=3", do both equations still remain equal to one another?

3. When you solve the equation for example as in the equation (change the letter y into a 3), is the answer correct and also equal to the other equation?

If all of these steps are true then your dealing with an Addition Property of Equality(APE).

well, michelle wanted to measure the height of her school's flagpole she placed a mirror on the ground 48 feet from the flagpole then walk backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft from the mirror using similar triangles find the height of the flagpole to the nearest tenth of a foot find the geometric mean of them pair of numbers. its easy math
