160+100+180+60=500
180/500=0.36=36%
50x36%=18
That's your answer lovely~
1. You need to make a proportion
2. Your proportion would be 8 over 10 equals X over 15
3. Your equation would be 10x=15(8)
4. 15x8=125
5. 10x=125
6. you would divide 125 by 10
7. thats your answer
Step-by-step explanation:

Answer:
I think it is 2x-3y<7, also, I used a free program called Desmos to figure it out, in case you also want to.
Step-by-step explanation:
Answer:
Option 3: 
Graph C
Step-by-step explanation:
Find the solution of 

(multiplication property of equality)
Divide both sides by -1. Since we are dividing by a negative number, the sign would change

This means that the possible values of x are 8 and any number above 8.
Graphing this, the arrow of directed line would start at 8 and move towards our right hand.
Thus, the graph would be graph C in option C.
