Answer:
C
Step-by-step explanation:
This question can simply be answered by the process of elimination. All of the other answers have numbers behind the first number of the decimal. when you are rounding to the nearest tenth, you will have no numbers behind the decimal except 1. They will look like this:
11.70
23.30
45.60
So, since we are looking for the nearest tenth, we would choose C because it is the only one that is rounded.
First, isolate 1/3s:
1/3s=12
Second, multiply both sides by 3 to get a singular value of s (just s):
s=36
It would be 15.4 -8.1 , hope this helps
