Distribute 7 to both n and 1
7(n + 1) = 7n + 7
5n + 7 = 7n + 7 - 2n
Combine like terms
5n + 7 = 7n - 2n + 7
5n + 7 = 5n + 7
If you want to solve for n, subtract 7 from both sides
5n + 7 (-7) = 5n + 7 (-7)
5n = 5n
then divide 5 from both sides
5n/5 = 5n/5
n = n
Effectively, this equation is <em>unsolvable</em>

Answer:
x = 5
Step-by-step explanation:
To solve, first subtract 5 from each side:
5 + 7x = 40
7x = 35
Then divide each side by 7:
x = 5
Answer:
1) B. The height appear to be reported because there are disproportionately more 0s and 5s.
2) A. They are likely not very accurate because they appear to be reported.
Step-by-step explanation:
The distribution table is shown below:
Last Digit Frequency
0 9
1 1
2 1
3 3
4 1
5 11
6 1
7 0
8 3
9 1
1. Based on the distribution table, we see a very disproportionate distribution. There is a high frequency of 0's and 5's. This lays credence to the heights being reported rather than measured. As such, option B is the correct answer
<u>B. The height appear to be reported because there are disproportionately more 0s and 5s</u>.
2. Since the heights were reported and not measured, they are most certainly not accurate. The conclusion is that the result is not accurate. As such, option A is the correct answer
<u>A. They are likely not very accurate because they appear to be reported</u>.
