1.) Let's say that the circle on the graph below represents x. The arrow is pointing to all the numbers greater than x, which happens to be on -2. If it points right, this means that x can equal to any number greater than -2. So your answer is x > -2.
2.) For inequalities such as these, you can simplify just like what you do for normal equations. Let's isolate x.

Answer:
6
Step-by-step explanation:
8.05 divided by 1.25 is 6.44
I think it would be 105
19+15+32+13+26
Cross multiply and set it up like this.
1800 X
------- • -------
80 24
Multiply 1800•24
Then divide by 80 and you get 540.
