Answer:
3x + 1/2x
Step-by-step explanation:
Just replace "a number" with x
"Three times x added to half x"
Given : supply voltage = 120V;60 Hz
Inductive Reactance
Ω
The inductive reactance is given by the formula,
, where L is inductance and
is given by formula, 
Apply this, we can say that, 
2/5 = x/10
2/5 x 2 = 4/10
x= 4
2/5 = 4/10
