10(1/2x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = - 52
x = -52/5

The probability of her getting a red marble is the number of red marbles divided by the number of total marbles. Since she picked a green marble first, we must subtract one marble from the total number of marbles, so that the total # of marbles is 6 + 6 + 4 = 16 - 1 (green marble) = 15. Since there are 6 red marbles, our probability is 6/15 or 2/5. Converted to percentage form, this is 0.4 —> 40%
Answer:
y = 3x - 2
General Formulas and Concepts:
Properties of Equality
Step-by-Step Explanation:
Step 1: Define equation
6x - 2y = 4
Step 2: Solve for y
1. Subtract 6x on both sides: -2y = 4 - 6x
2. Divide both sides by -2: y = -2 + 3x
3. Rewrite: y = 3x - 2
