Answer:
B
Step-by-step explanation:
Given
- 3x + 12 ≤ 15 ( subtract 12 from both sides )
- 3x ≤ 3
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity.
x ≥ - 1
Since x can equal - 1, we are looking for a solid circle at x = - 1 on the number line.
Since x greater than - 1 we require the shaded arrow to be pointing right.
Graph B represents this
Answer:
A, AA similarity
Step-by-step explanation:
the first similar angle is from the vertical angles and there are 2 more because the end sides are parallel and when they intersect with the same line it will make it have the same degree. It may look SAS but the figure may not be drawn to scale and there is no proof for it.
Answer: See below
Explanation:
6a + 11 = 2a + 83
6a - 2a = 83 - 11
4a = 72
a = 72/4
a = 18
Add them all up and divide by 30. Answer: $55.20.
