Answer:
Karson's average speed on his way home was 28 miles per hour.
Step-by-step explanation:
Since Karson drove from his house to work at an average speed of 35 miles per hour, and the drive took him 20 minutes, if the drive took him 25 minutes and he used the same route in reverse, to determine what was his average speed going home, the following calculation must be performed:
60 = 35
20 = X
20 x 35/60 = X
700/60 = X
11.666 = X
25 = 11,666
60 = X
60 x 11.666 / 25 = X
27.99 = X
Therefore, Karson's average speed on his way home was 28 miles per hour.
Answer:
D.) 12x + 3
Step-by-step explanation: What you have to do, is distribute the 4 inside the parentheses.
6 + 4(3x - 2) + 5
6 + 4(3x) - 4(2) + 5
6 + 12x - 8 + 5 -Now combine your like terms
6 + 12x - 3
12x + 6 - 3
12x + 3
Hope this helps you, and is the right answer.
