Answer:
<u>Jack has at least 15 marbles: 12 red, 2 blue and 1 yellow.</u>
Step-by-step explanation:
1. Let's review the information given to us to solve the problem correctly:
Number of red marbles = 10 more than blue marbles
Number of yellow marbles fewer than blue marbles
2. How many of each color marble could Jack have?
r = Number of red marbles
b = Number of blue marbles
y = Number of yellow marbles
r = b + 10
y < b
If y = 1, then b ≥ 2, and r = b + 10,
fulfilling the three conditions, we have:
<u>y = 1, b = 2, and r = 12</u>

Answer: A) Dashed line, shaded below</h3>
=============================================================
Explanation:
2x + 4y < 16 solves to y < -0.5x+4 when you isolate y. The inequality sign does not change direction because we divided both sides by a positive value (in this case, 4).
The graph of y < -0.5x+4 will be the same as the graph of 2x+4y < 16
To graph y < -0.5x+4, we graph y = -0.5x+4 which is a straight line that goes through the two points (0,4) and (2, 3). This is the boundary line of the inequality shaded region. The boundary line is a dashed line because we are not including points on the boundary that are part of the solution set. We only include these boundary points if the inequality sign has "or equal to".
We then shade below the dashed boundary line to indicate points below the boundary line. The shading is done downward due to the "less than" sign.
---------------------
Perhaps another method to find what direction we shade is we can try out a point like (0,0). The point cannot be on the boundary line.
Plug those coordinates into either equation. I'll pick the second equation
y < -0.5x+4
0 < -0.5*0+4
0 < 0+4
0 < 4
The last inequality is true, so the first inequality is also true when (x,y) = (0,0). Therefore, the point (0,0) is in the shaded region. The point (0,0) is below the boundary line y = -0.5x+4
So this is another way to see that the shaded region is below the boundary line.
the answer is C
Use the distributive property
Answer:
6 : 1
Step-by-step explanation:
divide by 3 on both sides
18 ÷ 3 = 6
3 ÷ 3 = 1
6:1
