Show Answer Key & Explanations Step-by-step solution for: One Step Inequalities Worksheets
It looks like you've uploaded a worksheet titled "One-Step Inequalities" that contains a grid of inequality problems. The instructions say:
> *"Cut out cards. Place the correct one-step solution next to each problem."*

However, since I can't view or access images directly, I’ll help you solve each inequality listed in the grid and explain how to solve them step-by-step.

Here are the inequalities from your image (based on what’s visible):

Grid of Inequalities



| 1. $-6x < 15$ | 2. $-18 > x - 20$ | 3. $x + 18 \geq 19$ |
|---------------|-------------------|---------------------|
| 4. $x + 37 > -36$ | 5. $-9x < -27$ | 6. $\frac{x}{2} \geq -2$ |
| 7. $-12x > 36$ | 8. $x - 14 < -12$ | 9. $-14x \leq 28$ |
| 10. $-9x + 36$ | 11. $x + 26 \geq 29$ | 12. $\frac{x}{3} < -1$ |

Wait — number 10 appears to be missing an inequality symbol. It says:
"-9x + 36", which is just an expression. That might be a typo. Let's assume it's meant to be something like:
$-9x + 36 > 0$ or $-9x + 36 \geq 0$? Since this is a one-step inequality, perhaps it was meant to be $-9x > -36$?

But looking at pattern, maybe it's supposed to be $-9x + 36 > 0$ → then solve:
$-9x + 36 > 0$ → $-9x > -36$ → $x < 4$

Let’s go through all the ones we can clearly interpret.

Now, let’s solve each inequality step by step.

---

1. $-6x < 15$



Divide both sides by $-6$.
Remember: When dividing by a negative number, reverse the inequality sign.

$$
x > \frac{15}{-6} = -\frac{5}{2}
$$

Answer: $x > -\frac{5}{2}$

---

2. $-18 > x - 20$



Add 20 to both sides:

$$
-18 + 20 > x \Rightarrow 2 > x
$$

Or: $x < 2$

Answer: $x < 2$

---

3. $x + 18 \geq 19$



Subtract 18 from both sides:

$$
x \geq 19 - 18 = 1
$$

Answer: $x \geq 1$

---

4. $x + 37 > -36$



Subtract 37:

$$
x > -36 - 37 = -73
$$

Answer: $x > -73$

---

5. $-9x < -27$



Divide by $-9$, reverse inequality:

$$
x > \frac{-27}{-9} = 3
$$

Answer: $x > 3$

---

6. $\frac{x}{2} \geq -2$



Multiply both sides by 2:

$$
x \geq -4
$$

Answer: $x \geq -4$

---

7. $-12x > 36$



Divide by $-12$, reverse inequality:

$$
x < \frac{36}{-12} = -3
$$

Answer: $x < -3$

---

8. $x - 14 < -12$



Add 14:

$$
x < -12 + 14 = 2
$$

Answer: $x < 2$

---

9. $-14x \leq 28$



Divide by $-14$, reverse inequality:

$$
x \geq \frac{28}{-14} = -2
$$

Answer: $x \geq -2$

---

10. $-9x + 36$Incomplete



This seems to be missing an inequality sign. Possible options:
- If it’s $-9x + 36 > 0$, then:
$$
-9x > -36 \Rightarrow x < 4
$$
- If it’s $-9x + 36 \geq 0$: $x \leq 4$

But since others are one-step, maybe it was meant to be $-9x > -36$?

Let’s assume it's $-9x > -36$ → same as #5 → $x < 4$

But #5 already has that.

Alternatively, maybe it’s $-9x + 36 \geq 0$ → $-9x \geq -36$ → $x \leq 4$

We'll go with that for now.

Assumed: $-9x + 36 \geq 0$ → $x \leq 4$

---

11. $x + 26 \geq 29$



Subtract 26:

$$
x \geq 29 - 26 = 3
$$

Answer: $x \geq 3$

---

12. $\frac{x}{3} < -1$



Multiply both sides by 3:

$$
x < -3
$$

Answer: $x < -3$
