For this case we have the following inequality:

The first thing we must do is to graph the linear function:

Then, we must evaluate ordered pairs in the following way:
(x, y)
The ordered pairs that meet the inequality, will be included as part of the graph.
Therefore, the shaded region contains all the ordered pairs that meet the inequality.
Answer: See attached image.
From what I'm reading from this question, there's one answer.
13 + 5 * 1 = 18
Unless maybe I'm missing something?
Let Surface Area A, a the base edge and h the height:
A = a²+2a√(a²/4+h²)
h=?
pythagorean theorem:
h²=c²-a²
h=√(c²-a²)
h=√(8²-(.7/2)²)= 8
plug it in the above equation A= 11.7ft²
So A is correct
5 red : 7 yellow
25 red: ? Yellow
5 x 5 is 25 therefore the multiplier is 5
We multiply 7 by 5 which is 35
Therefore 24 red : 35 yellow
35 yellow marbles
