Answer:
7, 17, 20, 11
Step-by-step explanation:
you just round each number to the nearest whole number and then add them
Answer:
1
Step-by-step explanation:
the reason why is because 16 people are coming to your party + you is 17
2x + (x + 5) = 30
3x + 5 = 30
3x = 30 - 5
3x = 25
x = 25/3
Answer:
See below ↓↓
Step-by-step explanation:
<u>Finding x</u>
- Both the angles containing the x variable are on the same side of the transversal
- There is a property which states that : two angles on the same side of the transversal are supplementary
- Therefore, they add up to 180°
- ⇒ 8x + 12 + 2x + 18 = 180
- ⇒ 10x + 30 = 180
- ⇒ 10x = 150
- ⇒ <u>x = 15</u>
<u></u>
<u>Finding y</u>
- The angles at the top are vertically opposite angles (VOA), meaning that they are equal
- ⇒ 8x + 12 = 3y - 18
- ⇒ 3y = 8(15) + 12 + 18
- ⇒ 3y = 120 + 30
- ⇒ 3y = 150
- <u>⇒ y = 50</u>
