The answer is 2. 2/4= 1/2
Answer:
f⁻¹(x) = eˣ / 3
Step-by-step explanation:
f(x) = In(3x)
y = In(3x)
swap x and y: x = In(3y)
solve y: eˣ = 3y
y = eˣ / 3
f⁻¹(x) = eˣ / 3
Use angle sum property (the 3 angles in a triangle sum up to 180°).
2x + x + 54 = 180
3x + 54 = 180
3x = 180 - 54
3x = 126
x = 126/3
x = 42

Let the common multiple be x
<span>3x : 2x </span>
<span>3x = 125 </span>
<span>x = 125/3 </span>
<span>So, B pays 2x = 2 × 125/3 = £250/3 </span>
