<u><em>y=3 is the correct answer.</em></u> First you had to remove parenthesis first. And it gave us, -3*2y=-18. Then multiply by the numbers. And it gave us, -6y=-18. Next, divide by -6 from both sides of equation. And it gave us, \frac{-6y}{-6}= \frac{-18}{-6}. And finally simplify, and it gave us the answer is y=3 is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

Answer:

We can see that it is an isosceles triangle so base angles are equal.

Step-by-step explanation:

x + x + 56 = 180

2x = 180 - 56

2x = 124

x = 124/2

Therefore x = 62.

34. x - 3 = 8x + 4
      -3 - 4 = 8x - x
      -7 = 7x
      -7/7 = x
      -1 = x

y = x - 3
y = -1 - 3
y = -4

solution is (-1,-4)
===================
35. -6 = -x - 2y
      x = -2y + 6

2 + 5x = -2y
2 + 5(-2y + 6) = -2y
2 - 10y + 30 = -2y
32 = -2y + 10y
32 = 8y
32/8 = y
4 = y

2 + 5x = -2y
2 + 5x = -2(4)
2 + 5x = -8
5x = -8 - 2
5x = -10
x = -10/5
x = -2

solution is (-2,4)
==================
36. 4x + 6y = 2000
       x + y = 410
==================
37. 4x + 6y = 2000
       x + y = 410......multiply by -6
----------------------
4x + 6y = 2000
-6x - 6y = - 2460 (result of multiplying by -6)
--------------------add
-2x = - 460
x = -460/-2
x = 230 <=== tickets in advance

Women jeans = 36

To find percent of all the jeans are women's skinny jeans
