Answer:
1) x = 12
2) x = 2
Step-by-step explanation:
Because each figure is a parallelogram, we know that the opposite sides are congruent. Now, we set 12 equal to 2x - 12 to solve. For number one, x = 12. For number two, we set 5x + 1 equal to -1 + 6x to solve. This equals 2.

The probability that the participant was a nonsmoker is 25%.
<h3><u>Probability</u> </h3>
Given that at the beginning of a certain study of a group of persons, 15% were classified as heavy smokers, 30% as light smokers, and 55% as nonsmokers, and in the five-year study, it was determined that the death rates of the heavy and light smokers were five and three times that of the nonsmokers, respectively, to calculate, if a randomly selected participant died over the five-year period, the probability that the participant was a nonsmoker, the following calculation must be performed:
- 15 x 5 = 75
- 30 x 3 = 90
- 55 = 55
- 55 + 90 + 75 = 220
- 220 = 100
- 55 = X
- 55 x 100 / 220 = x
- 5500 / 220 = X
- 25 = X
Therefore, the probability that the participant was a nonsmoker is 25%.

The missing number is 9. Pretty long equation..
F(2) = f(1) - 8 = 100-8 = 92
f(3) = f(1) - 2(8) = 100-16 = 84
so f(6) = f(1) - 5(8) = 60
