Get ReadyPrepárate
Wake up what you know, then explore today's model.
Activa lo que sabes y luego explora el modelo de hoy.
- On paper, solve x + 5 > 11. Predict whether the shading goes left or right of the boundary and whether the circle is open or closed. Then test one number from the shaded side and one from the other side. Write what each test shows.
- Which graph represents x > 8?
- Closed circle at 8, shaded right
- Open circle at 8, shaded right
- Open circle at 8, shaded left
- Closed circle at 8, shaded left
- Which graph represents x ≤ 10?
- Open circle at 10, shaded left
- Closed circle at 10, shaded left
- Closed circle at 10, shaded right
- Open circle at 10, shaded right
- Which graph represents x < 5?
- Closed circle at 5, shaded left
- Open circle at 5, shaded right
- Open circle at 5, shaded left
- Closed circle at 5, shaded right
- 1 fresh problem with new numbers each time (interactive only).

Use the hints when you need them. Every wrong answer tells you why.
Usa las pistas cuando las necesites. Cada respuesta incorrecta te dice por qué.
- Solve: x + 6 > 14
- x > 8

- x = 8
- x > 20
- Solve: x − 9 ≤ 3
- x ≤ 6
- x ≤ 12
- x ≥ 12
- x = 12
- Solve: x + 10 ≥ 25
- x ≥ 15
- x ≤ 15
- x = 15
- x ≥ 35

On Your OwnPor tu cuenta
Tables, mistakes to find, and problems with a few steps.
Tablas, errores por encontrar y problemas de varios pasos.
- Is x = 5 a solution to x + 4 > 12?
- No, because 5 + 4 = 9, and 9 is not greater than 12
- Yes, because 5 + 4 = 9
- Yes, because 5 > 4
- No, because 5 < 12
- Solve each inequality first, then sort by whether x = 10 is a solution.
- Catch the Open vs. Closed Circle Mistake
- What is the best next move?
- Add 9 to both sides.
- Subtract 9 from both sides, just as you would with an equation.
- Change > to < before solving.
- Replace > with = and stop at the first number you find.

- Solve 48 + s ≥ 75.
- s ≥ 27
- s ≤ 27
- s ≥ 75
- s ≥ 123
- Is exactly $27 enough?
- No — she needs more than 27
- Yes — 'at least' includes 27 exactly
- No — she needs 75
- Only if she saves more
- How is s ≥ 27 graphed?
- Closed circle at 27, shaded to the right
- Open circle at 27, shaded to the right
- Closed circle at 27, shaded to the left
- Open circle at 27, shaded to the left
