Answer:

x = 12/13

BC = 140/13

Step-by-step explanation:

If A is the mipoint of BC, then AB is half of BC.

AB = BC / 2

8x − 2 = (3x + 8) / 2

16x − 4 = 3x + 8

13x = 12

x = 12/13

BC = 3x + 8

BC = 3 (12/13) + 8

BC = 36/13 + 104/13

BC = 140/13

The sum of twice a number is at most 15. Write and solve. Give 3 possible whole number solutions.

Sveta_85 [38]

5 + 10 = 15

4 + 8 = 12

3 + 6 = 9

These are at most 15 bust not over 15

6 and above font work because they result in a number above 15

and 2 and below don't work because it is noticeably not close by observation.
