3 = -(-y + 6)

First, simplify brackets. / Your problem should look like: 3 = y - 6
Second, add 6 to both sides. / Your problem should look like: 3 + 6 = y
Third, simplify 3 + 6 to 9. / Your problem should look like: 9 = y
Fourth, switch sides. / Your problem should look like: y = 9

The answer is D) 9.

Answer:

6) x=9.75

10) Triangle OMN ~ Triangle ODK; SSS ~

11) SSS ~ theorem

12) SSS ~ theorem

Step-by-step explanation:

For #6, since the polygons are similar, then it must mean AD is congruent to JM and CD is congruent to LM. Now we can set up the proportion 39/20=x/5 and solve. Solving for x gets us x=9.75, so C is the correct choice

For #10, there's no information about angles whatsoever in the diagram, so B and C must be wrong. D must be wrong as well because if the triangles weren't similar, then why is OJ ~ JM and OK ~ KN? So thus, the triangles are similar by SSS.

For #11, this is sort of a no-brainer because there's no mention of angles, so D must be correct.

For #12, same concept, no mention of angles, all sides are similar to their respective sides of the different triangles, so A is correct.
