3y - 12x = 20
3y = 20 + 12x
y = (20/3) + 4x
Step-by-step explanation:
2x2 is 4 4x4 is 16 16x1 is 16
Answer:
Therefore the final elevation of the butterfly is 4 m.
Step-by-step explanation:
i) initial elevation = 20 m
ii) change in elevation = -16m
iii) therefore final elevation = initial elevation + change in elevation
= 20 m + (-16 m)
= (20 - 16) m
= 4 m
Therefore the final elevation of the butterfly is 4 m.
