Answer: Check explanation.
Step-by-step explanation: Let's say the equation is 4x ≥ 32, you can mark it on the number line with a filled in dot on 8 and arrow going to the right (increasing) forever. The dot indicates that the answer could be 8, and the arrow indicates it can be more than 8. Hope this helped!
you need to add for number one you need to subtract for number two you need to add for number 3 you need to subtract for number 4

We have 2 conditions:
1 - angles opposed by the vertex - the angles are equal
2 - supplementary angles - the sum of the two angles results in 180
2:
(4X + 15) and (5X + 30) are supplementary angles, so:
(4X + 15) + (5X + 30) = 180
9X = 180 - 15 - 30
9X = 135
<h2>X = 15</h2>
1:
(3Y + 15) and (5X + 30) are angles opposed by the vertex, so they are equal
3Y + 15 = 5X + 30
3Y = 5X + 30 - 15
3Y = 5X + 15 <em>above we have already calculated the value of X</em>
3Y = 5.(15) + 15
3Y = 75 + 15
3Y = 90
Y = 90/3
<h3>Y = 30</h3>
