Answer:
21
Step-by-step explanation:
The trip was 6 hours long.
Step-by-step explanation:
Given,
The time to go to the island = 1
hours.
The return trip took 3/4 of the time of the original trip.
To find the time of the trip.
Let,
The time of the original trip is x hours.
The time for returning = ![\frac{3x}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B4%7D)
According to the problem,
1
+
= x
or, x -
= ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
or,
= ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
or, x =
×4 = 6 hours
Hence,
The trip was 6 hours long.
2. So for this question, you do the distributive property, which is multiplying the term outside of the parenthesis by the terms in the parenthesis. In this case, the outside term is 1/2. 8x * 1/2 = 4x and 1/2 * -16 is -8. That brings us to 4x - 8, which is our answer. Therefore, the correct answer choice is B.
3. Okay. In this problem, we are talking about the sum of 12 and a number. That's 12 + n, because sum means the answer to the addition problem D is out, because we don't do distributive property in this case. The sum of 12 + n is 4n. The expression is 12 + n = 4n. The answer is B.
