First you would subtract 7 from each side to get -18. Then you would change the negative to a positive to make the x positive. X equals 18
The answer is 6.5

Answer:
k
Step-by-step explanation:
Answer:
- 1/243 ≈ 0.004 (which is a low probability)
Explanation:
The event landing on a three or four on a rolling is independent of the event of landing on a three or four on any other rolling.
Thus, for independent events you calculate the joint probability as the product of the probabilities of each event:
- P(A and B and C and D and E) = P(A) × P(B) × P(C) × P(D) × P(E)
Here, P(A) = P(B) = P(C) = P(D) = P(E) = probability of landing on a three or four.
Now to calculate the probability of landing on a three or four, you follow this reasoning:
- Positive outcomes = three or four
- Number of positive outcomes = 2
- Possible outcomes = one, two, three, four, five, or six
- Number of possible outcomes = 6
- Probability = numer of positive outcomes / numer of possible outcomes
Finally, probability of landing on a three or four on all five rolls: (1/3)⁵ = 1/243 ≈ 0.004 ← answer
The expression from the given options that is equivalent fraction -7/9 is -14/18.
<h3>What is a fraction?</h3>
Fraction can be described as the expression of numbers, which usually have the numerator and the denominator, and this do contains two integers arranged on each other.
From the given fraction,-7/9 if start o test the options by reducing them int their simplest form we will deduced that option B is correct because if we divide 14 by the factor of 2, and 18 by the factor of 2, then it will give us -7/9 which is a negative value of fraction in the question.
Therefore, option B is correct.
