Hello! So, for the first inequality, we have to add 10 to both sides. When you do that, 3.5x > 7. Then, you have to divide both sides by 3.5. When you do that, you get x > 2. Then, for the second inequality, you have to add 9 to both sides, then you would get 8x < 48. Divide both sides by 8 and you get x < 6. The compound inequality for this question would be 2 < x < 6.

Answer:
A, D, & F
Step-by-step explanation:
When you distribute, you get 6a + 5a + 5 - 3a + 21.
After combining like terms, you get 8a + 26.
Lastly, all you have to do is figure out which expressions are equivalent to
8a + 26.
A) 8a + 26 = 8a + 26
D) 6a + 5a + 5 - 3a + 21 (combine like terms) = 8a + 26
F) 2(4a + 13) - Simple distribution
2 x 4a = 8a
2 x 13 = 26
2(4a + 13) = 8a + 26
