What value of x is in the solution set of 2(3x – 1) ≥ 4x – 6?
shtirl [24]
<span>The answer is x ≥ -2. First use distributive property to simplify the left side of inequality: 2(3x – 1) ≥ 4x – 6. 2 * 3x - 2 * 1 ≥ 4x - 6. 6x - 2 ≥ 4x - 6. Rearrange it to get x on the one side and integers on the other side of inequality: 6x - 4x ≥ 2 - 6. Solve for x: 2x ≥ -4. x ≥ -4/2. x ≥ -2.Hope this helps. Let me know if you need additional help!</span>

How to know if an angle is congruent?
Svet_ta [14]

Answer:

Two angles are congruent if they have the same measure. If you didn't already know, when two lines intersect the vertical angles formed are congruent. For example, all the angles in a square are congruent. All the angles in a regular pentagon are 108°, therefore all the angles are congruent because they are the same.

Step-by-step explanation: Hope this helps:).........if not sorry:(
