You need to get x alone. So first you bring the 13 over and it becomes negative because it switches signs when switching sides
13x=104-13
13x=91
The you have to divide by 13 since you are multiplying on the other side
X=91/13
Your final answer should be
X=7

Answer: D. 0.69
Step-by-step explanation:
You can use SOHCAHTOA to find the right trigonometric identity to use:
Sine = opposite / hypotenuse
Cosine = adjacent / hypotenuse
Tangent = opposite / adjacent
The opposite side of angle A is side BC, which is 20 units long.
The hypotenuse is AB, which is 29 units long.
Opposite / hypotenuse = 20 / 29, which equals 0.689.
The correct choice is D.
20% is the the probability of a person taking the servey

Step-by-step explanation:
![6a - 4(2a + 3)\\6a - (4*2a + 4*3)\\6a - (8a + 12)\\6a - 8a - 12\\- 2a - 12\\\boxed{\bf\:2 (-a - 6)}](https://tex.z-dn.net/?f=6a%20-%204%282a%20%2B%203%29%5C%5C6a%20-%20%284%2A2a%20%2B%204%2A3%29%5C%5C6a%20-%20%288a%20%2B%2012%29%5C%5C6a%20-%208a%20-%2012%5C%5C-%202a%20-%2012%5C%5C%5Cboxed%7B%5Cbf%5C%3A2%20%28-a%20-%206%29%7D)
Steps:
- Factorise the second term as the first is already in its simplified form.
- Solve the first term and the second term by doing the required arithmetic operations.
- Take the common factor out.
- The result will be : 2 (- a - 6).
