**Answer:**

x = 26

**Step-by-step explanation:**

Cross-multiply => 12x = 13x - 26

Isolate x => -x = -26

Divide by -1 => x = 26

**Answer:**

dependent

**Step-by-step explanation:**

The given system is :

15x-18=3y

5x=y+6

Rewrite the equations in standard form to get:

15x-3y=18

5x-y=6

Multiply the bottom equation by 3.

15x-3y=18

15x-3y=18

Sub both equations:

0-0=0

0=0

We got an identity

The system is dependent because there are infinitely many solutions

**Answer:**

1) z - 42

2) 11k

3) t + 70

4) 43/m

5) w + 64

6) j - 100

7) g + 9

8) h - 17

9) 0.25v

I believe all of these are correct.

**Answer: ASA (angle side angle)**

Check out the attached image below. In that image, I marked the 2 pairs of congruent angles. I've also marked the pairs of sides that are between the two angles. I split up the triangles to help see the two sides better.

ASA is different from SAA because of the order of the letters. Notice how the S is between the two "A"s.
