Answer:
C
Step-by-step explanation:
we are just multiplying 6.1x0.12 it gives us 0.732 simple
5/8 or .625 is the answer
5(3) + 1/2(2)^2 - replace variables with parenthesis that contain the variable's amount.
15 + 1/2(4) - parenthesis/exponents, multiplication.
15 + 2 - addition left to right.
17. - final answer.
Remember PEMDAS, your answer will be 17.
Now that you know how to solve it, don't copy paste this post.
You'll get caught, I promise.
Now that you know PEMDAS, make an explanation.
Good luck.

Answer:
Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
Step-by-step explanation:
Let 
denote the number of rafts seating 3 people and 
the number of rafts seating 5 people. The total number of rafts is 13, so 
. We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so 
.
It's always a good idea to put these equations under each other:
We can subtract the first equation three times from the second one to obtain 
Now, substitute this found value for into 
and we see that 
. We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
