Answer:

x = - 1

Step-by-step explanation:

Given

2(3x - 1) ≥ 4x - 6 ← distribute parenthesis on left side

6x - 2 ≥ 4x - 6 ( subtract 4x from both sides )

2x - 2 ≥ - 6 ( add 2 to both sides )

2x ≥ - 4 ( divide both sides by 2 )

x ≥ - 2

The only value in the list greater than - 2 is - 1

x = - 1 is in the solution set

Answer:

140°

Step-by-step explanation:

Angles 1 and 3 are "corresponding" angles, so are congruent.

∠1 = ∠3

20x +60 = 30x +20

40 = 10x . . . . . . . . . . . . subtract 20x+20

4 = x . . . . . . . . . . . . . . divide by 10

∠1 = 20x +60 = 20(4) +60 = 80 +60

∠1 = 140°
