Q: George has 40 bananas now. He wants to have at least 25 bananas at the end of the week. Write an inequality for the number of bananas, b, George can eat this week.
- 40 + b < 25 (Eating bananas would be subtraction.)
- 40 - b < 25 (George wants to have 25 bananas or more left at the end of the week.)
- 40 - b > 25 ("At least 25 bananas" means that 25 bananas would be enough.)
- 40 - b > 25
A: 40 - b > 25

Q: You and your friend shot some basketball free throws. Together you made less than 40 shots. Your friend made 12 shots. Write an inequality for the number of shots, s, you might have made.
- s + 12 > 40 (Together you made less than 40 shots)
- s + 12 < 40
- 12s < 40 (You need to add your shots to your friend's shots. Multiplying two amounts of basketball shots together does not make sense.)
- s - 12 < 40 (Together you made the shots. You need to add your friend's shots to yours.)
A: s + 12 < 40

Q: You and your friend shot some basketball free throws. Together you made less than 40 shots. Your friend made 12 shots. Solve for s, the number of shots you made.
A: s < 28 / s<28 / s< 28 / s <28
Partly right: 28 (25%); s > 28 (25%)
Feedback ("28"): You need to write the inequality that is the solution. Use s. Remember you could have made 27 shots or 20 shots or 5 shots or...
Feedback ("s > 28"): Together you made less than 40 shots. The solution should have a less than sign.

Q: Is x = 4 a solution to the inequality  x - 5 < 2 ?
- Yes
- No
A: Yes

Q: Is x = -2 a solution to the inequality  x - 3 > 0 ?
- Yes
- No
A: No

Q: Is x = -1 a solution to the inequality  x - 3 > -4 ?
- Yes
- No (Notice that the inequality symbol is >, greater than or equal to. That means it can be equal.)
A: Yes

Q: Is  x = 5  a solution to the inequality  -8 + x < -3 ?
- Yes (The inequality symbol is <. so the left side can't be equal to -3.)
- No (Good job. The inequality was <, so the left side can't be equal to -3.)
A: No

Q: Solve the inequality and graph the solution on a number line.

- x < 6 [Image] (correct)
- x > -6 [Image] (incorrect)
- x ≤ -6 [Image] (Good job!)
- x ≥ -6 [Image] (incorrect. You divided both sides by a negative, so you need to switch the inequality symbol.)
A: x ≤ -6 [Image]
