A.
The student mislabeled the work in the second step as "Addition property of equality."
B.
The student improperly applied the addition property of equality in the second step.
C.
The student computed the sums improperly to arrive at an erroneous answer in step 3.
(D.
There is no error. The student's justification is correct.)
The number of miles is the circumference of the Earth is 24810.60 miles.
Given that, the circumference of the Earth is approximately feet.
The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its centre. A meridian is any great circle passing through a point designated a pole.
In 1 mile = 5280 feet
Now, the number of miles =
= 131000000/5280
= 24810.60 miles
Therefore, the number of miles is the circumference of the Earth is 24810.60 miles.

Answer:
First, divide 1.31 x 108 by 5,280 and the result is 2.48 x 104.
2.48 x 104 miles
Step-by-step explanation:
12. 10+ x = 5 (1/5x + 2)
13. 8 (x + 2) = 2x + 16
14. 3+ 3/2x + 4 = 4x – 5/2x
15. 3/2 (2x +6) = 3x +9
16. ½ (2-4x) +2x = 13
17. 12 + 2x – x = 9x +6
18. 4x +1 = 2 (2x + 3)
19. 4 (x + 3) - 4 = 8(½x + 1)
20. X + 5x + 4 = 3(2x – 1)
21. 5 (x + 2) - 3x = 2 (x +5)

Answer:
the answer is C
Step-by-step explanation:
19.65 + 2.35 is exactly 22, not including tax
Answer:
A and C
Step-by-step explanation:
A. 15% off $25
15% = 0.15
0.15 x 25 = 3.75
25 - 3.75 = 21.25
22 or under? Yes
B. 30% off $32
30% = 0.30
0.30 x 32 = 9.60
32 - 9.60 = 22.40
22 or under? No
C. $19.65 plus a 2.35 shipping fee
19.65 + 2.35 = 22
22 or under? Yes
D. $20.45 plus a $1.60 shipping fee
20.45 + 1.60 = 22.05
22 or under? No
Even though this is late, the other answer did not mention A being the answer as well so I hope this helped!
