Answer: (-0.3) + 0.9= 0.6
Step-by-step explanation:
Sorry a bit messy, with a ratio of 2:5:1, that means 5 would be the longest and your longest piece is 125, diving 125 by 5 gets you 25 cm, this is also your shortest piece since 1x25=25
Well
one possible thing is if
a=1992
and if b or c or d =0
examples
a=1992
b=0
c=0
d=0
another is if a=b=c=1
and d=1989
there are many possibilities

Steps To Solve:
-27 + m = 3m + 9
~Subtract m to both sides
-27 + m - m = 3m + 9 - m
~Simplify
-27 = 2m + 9
~Subtract 9 to both sides
-27 - 9 = 2m + 9 - 9
~Simplify
-36 = 2m
~Divide 2 to both sides
-36/2 = 2m/2
~Simplify
-18 = m
------------------------------------------------
Answer:
m = -18
