A is the correct choice. Algebraic expression 6n-17
Probability of an event= number of ways an event can occur / total number of possible outcomes.
Probability = 6/12 = 0.5
Answer:
Step-by-step explanation:
<u>We know that the perimeter is the sum of side lengths.</u>
<u>Substitute the values and solve for x:</u>
- x + 2x - 2 + 3x + 1.5 = 11.5
- 6x - 0.5 = 11.5
- 6x = 12
- x = 12/6
- x = 2
