Answer Key — Math 7 (Grade 7) Midterm — Units 1–2
- C — 12 cups 8 is 4 times 2, so use 4 × 3 = 12 cups of flour.
- C — y = 4x Only y = kx form is proportional; y = 4x has k = 4 and no added constant.
- D — 87.5 miles 3.5 × 25 = 87.5 miles.
- C — 50 miles per hour Divide distance by time: 150 ÷ 3 = 50 miles per hour.
- C — 7 In y = kx, k is the constant of proportionality, so k = 7.
- D — x: 2, 4, 6; y: 5, 10, 15 Every y ÷ x equals 2.5, so the ratio is constant.
- C — 2.5 r is the unit rate: 10 ÷ 4 = 2.5.
- C — The 16-ounce box costs less per ounce $3.00 ÷ 12 = $0.25 per ounce; $3.60 ÷ 16 = $0.225 per ounce.
- D — A straight line that passes through the origin Proportional relationships graph as straight lines through (0, 0).
- D — 2 (1/2) ÷ (1/4) = 2 miles per hour.
- D — 0.375 Divide 3 by 8 to get 0.375.
- A — -4 Multiply first: -2.5 × 4 = -10. Then -10 + 6 = -4.
- A — -1/4 Rewrite 1/2 as 2/4: -3/4 + 2/4 = -1/4.
- B — 42 A negative times a negative is positive: 6 × 7 = 42.
- D — -7°F 4 - 11 = -7, so the temperature was -7°F.
- D — (-2)(-3)(-1) Three negative factors give a negative product: -6.
- A — -3/2 Multiply by the reciprocal: (-2/3)(9/4) = -18/12 = -3/2.
- D — 14 Subtracting a negative is adding: 5 + 9 = 14.
- B — -3 Signs differ: subtract 8 - 5 = 3 and keep the sign of -8.
- B — -25 feet -30 + 12 - 7 = -25 feet.
Written Response — Look-Fors
- Expression -4.5 + 4(2.5) - 7.25; 4(2.5) = 10; -4.5 + 10 = 5.5; 5.5 - 7.25 = -1.75. Final answer: -1.75°F.
