Answer:
-1
Step-by-step explanation:
5^(3b-1) = 5^(b-3)
3b-1=b-3 / +1 -b
2b = -2
b = -1
Let the longer piece be x+5
Let the shorter piece by x
Both the wires together make 31cm so
x + x + 5 = 31
2x + 5 = 31
2x = 26
x=13
The shorter piece of the wire is 13cm.

Explanation:
The statement is expressed as
y
∝
1
x
inverse means
1
variable
To convert to an equation introduce k, the constant of variation.
y
=
k
×
1
x
⇒
y
=
k
x
To find k use the given condition that y = 8 when x = 4
8
=
k

⇒
k
=
