13x + 6 = 6
Use the subtraction property of equality:
13x +6 -6 = 6-6
13x = 0
Now use the division property of equality:
You can use the recipricol and multiply:
13/1 13x = 0 × 13/1
x = 0/1
You can check by substituting 0/1 for x.
AB+BC+AC-12=AC+CD+AD
AB+BC-12=CD+AD
AB+BD+CD-12=CD+AD=BD
AB+BD-12=0
AB=12cm
Answer:
m ∠ 3 = 30°
Step-by-step explanation:
5x = x + 24 (opposite angle)
5x - x = 24
x = 24/4
x = 6
m ∠ 3
x + y = 180
y = 180/6
y = 30°
