So are you supposed to draw the graph or chose from multiple options? I included a graph of the problem (excuse the messy writing and graph) that's what it should kinda look like:
Let x be the fifth number

⇔

⇔ 23.3 + x = 34
⇔ x = 10.7
Answer:
its 0=0 1=3 and 2=3
Step-by-step explanation: count how many of the injuries there are for 0. In this case there is none. so how many 1's are there, 3. so put 3 in 1. Now two there is 3 for 2 so put 3 in the 2.
The x (the second one) has a one in front of it so 5x *1x=5x so 5x-4 is the answer
