A. x <= -12
<u>Explanation:</u>
-3x >= 36
-x >= 36/ 3
-x > = 12
x < = -12
When the negative sign is shifted then the greater than equal to sign reverses to less than equal to.
Therefore, x <= -12
Answer:
Statement 4 is incorrect.
Step-by-step explanation:
#4 is incorrect. This statement is assuming that both 3x+5 and 4x are equal, but the correct way to use them and achieve 180 (definition of supplementary) degrees is by writing it as: 3x+5 + 4x = 180. (I spaced the 3x+5 and 4x to make it clear that these are two angles added together.) With this equation, you will be able to find the x and the substitute it back in to complete the equation.
5/7 ÷ 1/3 = 5/7 × 3/1 = 15/7
Answer: x = 6
Formula: 
Step-by-step explanation:
We know that an area of a triangle is half of a rectangle.
The bottom side must equal 11, since if the figure was a rectangle, the area would be multiplied by 2, giving us 44.
What minus 5 equals 11?
6.
So x must equal 6.
