Answer:
Step-by-step explanation:
x = small barrettes
y = large barrettes
13x + 11y = 142.......multiply by -1
13x + 12y = 149
-----------------------
-13x - 11y = -142 (result of multiplying by -1)
13x + 12y = 149
------------------------add
y = 7..........large barrettes used 7 yards
13x + 11y = 142
13x + 11(7) = 142
13x + 77 = 142
13x = 142 - 77
13x = 65
x = 65/13
x = 5........small barrettes used 5 yards
5x-2=4x+17
x=19
<A (Left angle)= 93°
<B (Right angle)= 93°
Vertical angles are always =

162 km : 60 min
60 divided by 60 = 1
162 divided by 60 = 2.7
2.7 km a second
2.7 km = 2,700 m
2,700 m/second
2,700 m times 20 = 54,000 m in 20 seconds.
