Answer:
x is equal to 30
<ABC is equal to 100°
<DBC is equal to 80°
Step-by-step explanation:
3x +10 +2x +20 =180
5x = 180 - 10- 20
5x = 150, divide both sides by 5
x is equal to 30
<ABC = 3x + 10 = 3 × 30 + 10 = 100°
<DBC = 180 - <ABC = 180 - 100 = 80°
Answer:
One solution
Step-by-step explanation:
5x-8 = 3x+8
2x = 16
x = 8 = true once
6x-2>4x-6
2x-2>-6
2x>-4
X>_ -2
Answer:
