Answer:
x = 165, y = 15
Step-by-step explanation:
1. Well, what does supplementary mean? - The angles add up to 180°.
2. Let's form an equation: x + y = 180°
3. Let's say x is the larger angle and y is the smaller angle.
4. Let's form another equation: x = 150 + y
5. Put the two equations next to each other:
x + y = 180
x = 150 + y
6. We know what x is equaled to, so let's plug it into the first equation!
150 + y + y = 180
150 + 2y = 180
-150 -150
2y = 30
y = 15
7. Now, we know what y is, let's find x!
x + 15 = 180
-15 -15
x = 165
Maybe if you payed attention in class you would know.
Top right
this is because, when dividing an inequality by a negative number, you must flip the inequality sign
-3x < 21
x > -7
I think the answer is 62 because 7+5=12 4*13=52 12+52=64 64-2=62
What are you trying to ask. I am good at graphing so if I understand the question I can help
