Answer:
6
Step-by-step explanation:
Rule for divisibilty of 6:
- sum of place values is a multiple of 3
- an even number
Step 1: dd the integers
- 7 + 6 + 8 + 7 + 2 + x
- 30 + x
Now, we have a couple options:
You can use any of these three values,
But the number has to be even, so the last digit has to be even. The correct answer is 6.

Answer: When t = 4.25 R(t) = D(t)
This tells you that at 4.25 seconds into their flights, both the Rocket and the Drone were at a height of 20 feet.
Step-by-step explanation: The point where the two graphed lines cross is where the values are equal.
The Drone has been hovering at 20 feet between 2 and 5 seconds. The Rocket passed through that height for a brief (millisecond) time as it was falling back to the ground.
Without grid lines it is my best estimation (using a ruler to create a verticla line from the intersection of the lines to the time scale) that t = 4.25. It is between 4 and 4.5 seconds.
I think there are two solutions, 63 or 147:
63 = 3² x 7, factors 1 | 3 | 7 | 9 | 21 | 63<span>
147 = 3 x 7</span>², factors 1 | 3 | 7 | 21 | 49 | 147
Answer:
I think -3.5 is the right answer
