Answer:
x=9
Step-by-step explanation:
Similar triangles
8/20 = 6/(x+6)
==> 2/5 = 6/(x+6)
2/5x+12/5=6
2/5x=18/5
x=9
Answer:
x = -8
Step-by-step explanation:

x =-6
The first thing you want to do is to multiply both sides by 4:
3x=-24
Next you need to divide by 3:
x=-8
The answer is -8
Number times landing on green) = 150 * 1/5 = 30
Number times landing on yellow = 150 * 1/5 = 30
Answer 60 times
