HELP PLSS I NEED THE ANSWERS ASAP PLSSS :((

Step-by-step explanation:

The Hint said to find the two things in comparison

they are:

cross multiply the two equations

=99km*12lit=9lit*Xkm

=1188lit/km=9Xlit

note;

liters will annul liters

hence,

X=1188km/9

X = 132km

is the final answer

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

i agree because i see the other persons thinking is clear
