Time for light A's Flash = 4 seconds
Time for light B's Flash = 6 seconds
Duration between the lights = 6-4=2
Duration to flash again = LCM of 6, 4
2/6,4
2/3,2
3/3,1
/1,1
2x2 x 3
4 x 3
= 12 seconds
Answer:
angle b+54 = 90 degrees
90 - 54 = b
36° = angle b
60.
Step-by-step explanation:
B=5 units that is the answer
No solution
4x + y = -2
-20x - 5y = -3
<u><em>Using the Elimination method </em></u>
(4x + y = -2 ) 5
20x + 5y = -10
-20x - 5y = -10
0 = -10
No Solution
