I'm assuming you didn't mean to repeat each number 3 times.
If she did 184 jumping jacks in 4 minutes that means she did 46 jumping jacks per minute.
Fun fact
if f(a)=b then f⁻¹(b)=a
so
if f⁻¹(b)=a then f(a)=b
so we find f(x)=27 and the solve for x
f(x)=3x=27
3x=27
divide both sides by 3
x=9
so if f(9)=27 then f⁻¹(27)=9
problem solved
answer is 9
160 is the number i believe, hope it helps
Answer:
if a·b=0, then either a=0 or b=0, or both
