Let's solve each of the linear inequalities step by step.
---
1. $ 7w \leq 42 $
Step: Divide both sides by 7
$$
w \leq \frac{42}{7} = 6
$$
✔ Solution: $ w \leq 6 $
---
2. $ \frac{k}{4} \leq -4 $
Step: Multiply both sides by 4
$$
k \leq -4 \times 4 = -16
$$
✔ Solution: $ k \leq -16 $
---
3. $ -5 > \frac{p}{8} $
Step: Multiply both sides by 8
$$
-5 \times 8 > p \Rightarrow -40 > p
$$
or equivalently:
$$
p < -40
$$
✔ Solution: $ p < -40 $
---
4. $ 15 < r + 14 $
Step: Subtract 14 from both sides
$$
15 - 14 < r \Rightarrow 1 < r
$$
or:
$$
r > 1
$$
✔ Solution: $ r > 1 $
---
5. $ 3k \geq -24 $
Step: Divide both sides by 3
$$
k \geq \frac{-24}{3} = -8
$$
✔ Solution: $ k \geq -8 $
---
6. $ -6 \geq \frac{m}{4} $
Step: Multiply both sides by 4
$$
-6 \times 4 \geq m \Rightarrow -24 \geq m
$$
or:
$$
m \leq -24
$$
✔ Solution: $ m \leq -24 $
---
7. $ \frac{t}{6} < -3 $
Step: Multiply both sides by 6
$$
t < -3 \times 6 = -18
$$
✔ Solution: $ t < -18 $
---
8. $ -5 < \frac{1}{3}t $
Step: Multiply both sides by 3
$$
-5 \times 3 < t \Rightarrow -15 < t
$$
or:
$$
t > -15
$$
✔ Solution: $ t > -15 $
---
9. $ -6 < s - 11 $
Step: Add 11 to both sides
$$
-6 + 11 < s \Rightarrow 5 < s
$$
or:
$$
s > 5
$$
✔ Solution: $ s > 5 $
---
10. $ x + 14 \geq -5 $
Step: Subtract 14 from both sides
$$
x \geq -5 - 14 = -19
$$
✔ Solution: $ x \geq -19 $
---
✔ Final Answers:
1. $ w \leq 6 $
2. $ k \leq -16 $
3. $ p < -40 $
4. $ r > 1 $
5. $ k \geq -8 $
6. $ m \leq -24 $
7. $ t < -18 $
8. $ t > -15 $
9. $ s > 5 $
10. $ x \geq -19 $
