Step-by-step explanation:
<u>Step 1: Define Equation</u>
2(6x + 4) - 6 + 2x = 3(4x + 3) + 1
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 12x + 8 - 6 + 2x = 12x + 9 + 1
- Combine like terms: 14x + 2 = 12x + 10
- Subtract 12x on both sides: 2x + 2 = 10
- Subtract 2 on both sides: 2x = 8
- Divide 2 on both sides: x = 4
Positive × Positive = Positive
3 × 2 = 6
m × n = mn
Positive × Negative = Negative
8 × -4 = -32
m × -n = -mn
Negative × Negative = Positive
-5 × -4 = 20
-m × -n = mn
(-x) × (-x) = x²
The same rules apply for division as multiplication.
To find the probability, you need to divide the amount of red marbles by the total amount of marbles.
1/10 = 0.1.
The probability of choosing a red marble is 0.1, or 10%
