Answer:
a. 29
b. 9.1
Step-by-step explanation:
General = The perimeter is all the sides added togther.
a. x is given to you, so you just add all the numbers.
b. Now the perimeter is given, but not x. So add the numbers you can see. That would be 9+6.5+4.7= 20.2
So something + 20.2 has to equal 29.3
29.3 - 20.2 = 9.1.
I did not answer c. because I'm not very confident that my answer would be right. With my explainaion I hope you can figure it out easily enough. Good Luck!

Trains depart after every 4 minutes.
Total time train takes to complete a circuit= 24 minutes
Evan sets off at 8:30 am, so he will be back at 8:54 am.
So time of trains coming in opposite direction:
8: 34 am
8:38 am
8:42 am
8:46 am
and 8:50 am
5 trains coming in opposite directions.
Now the trains started at 8:06 am from the stations are:
8:06 am
8:10 am
8:14 am
8:18 am
8:22 am
and 8:26 am.
So there are 6 trains started the circuit at 8:06 am.
Now total number of trains=6+5=11 trains
Answer: 11 trains will pass on complete circuit.
