Solution

Here are the solutions to the inequalities in the uploaded image:

6) Solve:

103(5b6)9b5+810 - 3(-5b - 6) \leq -9b - 5 + 8

  1. Expand the terms:
    10+15b+189b+310 + 15b + 18 \leq -9b + 3

  2. Combine like terms:
    28+15b9b+328 + 15b \leq -9b + 3

  3. Add 9b9b to both sides:
    28+24b328 + 24b \leq 3

  4. Subtract 28 from both sides:
    24b2524b \leq -25

  5. Divide by 24:
    b2524b \leq -\frac{25}{24}


7) Solve:

3q(5q+1)>5q75q3q - (5q + 1) > -5q - 7 - 5q

  1. Expand the terms:
    3q5q1>10q73q - 5q - 1 > -10q - 7

  2. Combine like terms:
    2q1>10q7-2q - 1 > -10q - 7

  3. Add 10q10q to both sides:
    8q1>78q - 1 > -7

  4. Add 1 to both sides:
    8q>68q > -6

  5. Divide by 8:
    q>34q > -\frac{3}{4}


8) Solve:

5n+2(3n1)n9+5n-5n + 2(-3n - 1) \geq n - 9 + 5n

  1. Expand the terms:
    5n6n2n9+5n-5n - 6n - 2 \geq n - 9 + 5n

  2. Combine like terms:
    11n26n9-11n - 2 \geq 6n - 9

  3. Subtract 6n6n from both sides:
    17n29-17n - 2 \geq -9

  4. Add 2 to both sides:
    17n7-17n \geq -7

  5. Divide by 17-17 (flip the inequality):
    n717n \leq \frac{7}{17}


9) Solve:

7+5(4k10)>9k+287 + 5(-4k - 10) > -9k + 2 - 8

  1. Expand the terms:
    720k50>9k67 - 20k - 50 > -9k - 6

  2. Combine like terms:
    20k43>9k6-20k - 43 > -9k - 6

  3. Add 9k9k to both sides:
    11k43>6-11k - 43 > -6

  4. Add 43 to both sides:
    11k>37-11k > 37

  5. Divide by 11-11 (flip the inequality):
    k<3711k < -\frac{37}{11}


10) Solve:

6v5(8v8)<7v710v6v - 5(8v - 8) < 7v - 7 - 10v

  1. Expand the terms:
    6v40v+40<7v710v6v - 40v + 40 < 7v - 7 - 10v

  2. Combine like terms:
    34v+40<3v7-34v + 40 < -3v - 7

  3. Add 34v34v to both sides:
    40<31v740 < 31v - 7

  4. Add 7 to both sides:
    47<31v47 < 31v

  5. Divide by 31:
    v>4731v > \frac{47}{31}
