Answer:

Number of yellow marbles = 6

Number of purple marbles  =  24

Step-by-step explanation:

Number of yellow marbles = x

Number of purple marbles  = 3x + 6

Total marbles = 30

x + 3x+6 = 30

4x + 6 = 30

      4x = 30 - 6

      4x = 24

        x = 24/4

      x = 6

Number of yellow marbles = 6

Number of purple marbles  = 3 * 6 + 6 = 18 + 6 = 24

Leya [2.2K]

The solution to the system of inequalities is (-3.375, 1.75)

<h3>How to graph the inequalities?</h3>

The system of inequalities is given as:

3y > 2x+12

2x+y < -5

Next, we plot the graph of the system using a graphing tool

From the graph, both inequalities intersect at
