- D — Distributive Property Multiplying 5 by each term inside the parentheses is distributing.
- A — y = -(3/2)x + 4 2y = -3x + 8, then divide every term by 2.
- D — h = 2A/b Multiply both sides by 2, then divide by b.
- D — x = 6 6x + 3 = 4x + 15 gives 2x = 12, so x = 6.
- A — x = 21 Add 4: (2/3)x = 14. Multiply by 3/2: x = 21.
- B — x = 8 or x = -2 x - 3 = 5 or x - 3 = -5, so x = 8 or x = -2.
- B — 7x - 7 8x - 12 - x + 5 = 7x - 7.
- C — 6 2(-3)² - 3(4) = 2(9) - 12 = 6.
- D — x = 35 0.4x - 4 = 0.2x + 3 gives 0.2x = 7, so x = 35.
- B — 28 n + (n + 1) + (n + 2) = 87 gives 3n = 84, so n = 28.
- A — -5 < x < 5 Values within 5 units of zero lie between -5 and 5.
- A — 5 3(5) - 5 = 10, and 10 ≥ 10 is true.
- C — x ≥ -6 2x - 2 ≤ 3x + 4 gives -6 ≤ x.
- B — x < -4 -4x > 16; dividing by -4 reverses the sign: x < -4.
- A — 300 35 + 0.05t ≤ 50 gives 0.05t ≤ 15, so t ≤ 300.
- B — -2 < x ≤ 4 Subtract 1 from all parts, then divide all parts by 2.
- D — x < 2 Open circle means 2 is excluded; shading left means less than.
- A — (0, 0) 0 > 2(0) - 1 means 0 > -1, which is true.
- C — n - 7 ≤ 15 "Decreased by 7" is n - 7, and "at most" means ≤.
- A — x ≤ -1 or x ≥ 5 x - 2 ≤ -3 or x - 2 ≥ 3, so x ≤ -1 or x ≥ 5.
