The following examples illustrate the associative property of addition.
(5 + 2) + 3 = 5 + (2 + 3)
3.5 + (1.2 + 9.6) = (3.5 + 1.2) + 9.6
study the examples, then choose the statement that best describes the property.

Ac contractor is building a new subdivision outside of the city. he has started work on the first street and is planning on the other streets to run in a direction parallel to the first. the second street will pass through (-2,4) find the equation of the location of the second street in standard form. a.2x+y=2 b. x-y=2 c.2x+y=2 d.x+y=2

In the figure shown below, m < 40 and ab =8. which equation could be used to find x?
