Answer:
t = -10
Step-by-step explanation:
Ok so,
12 - 10t = -13t -18
12 - 10t + 13t = -13t + 13t - 18
12 + 3t = -18
12 - 12 + 3t = -18 - 12
3t = -30
t = -10
hope this helps! have a good day!

Answer:
<em>Gerry arrived at the bus station at 12:30 P.M.</em>
Step-by-step explanation:
From noon and 5:00 P.M. there are 5 hours.
Gerry, Dale, and Pat arrived at the bus stop within that interval, which means the sum of the times elapsed between their arrival times must be 5.
4 out of the 5 hours elapsed since Gerry and Dale's arrivals. This means there is only one hour left for twice x.
If twice x is one hour, then x is half an hour. Thus, the complete sequence of arrivals is:
Gerry arrived at the bus station at 12:30 P.M.
Dale arrived at the bus station at 4:30 P.M.
Pat arrived at the bus station at 5:00 P.M.
3x+9=36
with 2 times 9kg and 18kg is the solution:
I:2x+y=36
II:y=x+9
if you substitute y of II into I:
3x+9=36
3x=27
x=9
-> 2 boxes with 9kg and 1 with 9+9=18 kg
2*9+18=36kg in total
so the third option/Rashid is the solution
