Answer 1

1. 4x + 6 < -6
4x < -6 - 6
4x < -12
x < - 3

2. - 2/5 x - 9 < 9/10
- 2/5 x < 9/10 + 9
- 2/5 x < 99/10
x > (99/10) divided by - 2/5
x > 99/10 x - 5/2
x > - 99/4

3. q + 12 - 2(q - 22) >0
q + 12 - 2q + 44 > 0
- q +56 > 0
(-1) -q > - 56
q < 56

Answer 3

But # 2 Should Be x> -24 3/4. I Just Need To Know How The Teacher Got This Answer.

Answer 4

The answer I got was x > - 99/4 which when changed from an improper fraction to a mixed number is - 24 3/4. Some teachers prefer improper fractions while others prefer mixed numbers. Your teacher prefers mixed numbers therefore the answer is x > - 24 3/4.
