The value of x is 
Explanation:
The given expression is 
We need to find the value of x.
To determine the value of x, let us solve the expression for x.
Multiplying the term 3 within the bracket, we have,
Simplifying, we get,
Adding both sides of the expression by 13x, we have,
Adding both sides of the expression by 18, we get,
Dividing both sides of the equation by 21, we get,
Thus, the value of x is
Y > -4 on a graph will be a doted vertical line that goes trogh -4 and shade to the left since y is greater then -5, -6, -7,...etc.

Answer:
36
Step-by-step explanation:
There are 30 red marbles and the ratio of black to yellow is 4/5, so 4/5=orange/green=orange/30.
30 is 6 times 5, so black=6 times 4=24. There are 24 black marbles.
Total of black and yellow=24+30=54.
40% of the marbles are green so 60% are black/yellow. Also 60% is 54 marbles.
60% is 60/100=3/5 so 3/5 of the total is 54 marbles, therefore 1/5 is 54/3=18 and 2/5 is the number of red marbles=2 times 18=36 red marbles.
to be honest i can't think of anything original for the visual thing, but i think the pi chart from the person above me would work well
81/3 beacuse you are splitting up 81 among 3 equal rows
