Answer: The opposite of the opposite of a number is the number itself. And the opposite of the opposite of a number is the number itself.
Step-by-step explanation:
For this case we have the following inequality:

To find the solution we follow the steps below:
We apply distributive property on the right side of inequality:

Adding 13 to both sides of the inequality we have:

We subtract 6x on both sides of the inequality:

Thus, we have that any value of "x" makes the inequality fulfilled. Thus, the solution is given by all real numbers.
Answer:
The solution set is (-∞,∞)
Answer:
x=12
Step-by-step explanation:
3x=2x+12
3x-2x=12
x=12
You multiply 12x8.3 and get the answer 100
Answer:
A. 3/2
Step-by-step explanation:
To find the lenght of the side opposing the 30° angle, you need to use trigonometry, since it's a right-angled triangle. You have your 30° angle and you have the side beside : therefore, you can use the sine :
sin(30) x 3 = ?
0,5 x 3 = ?
1,5 = ?
1,5 = 3/2
