You're on a roll — here are the solutions for the number sentences: 1. Step 1: Rewrite the equation to isolate the unknown. 1172 - = 271 = 1172 - 271 Step 2: Perform the subtraction. = 901 The correct value is 901. 2. Step 1: Rewrite the equation to isolate the unknown. × 3 = 396 = (396)/(3) Step 2: Perform the division. = 132 The correct value is 132. 3. Step 1: Subtract 3 from both sides of the equation. 42 ÷ + 3 = 9 42 ÷ = 9 - 3 42 ÷ = 6 Step 2: Rewrite the equation to isolate the unknown. = (42)/(6) Step 3: Perform the division. = 7 The correct value is 7. 4. Step 1: Rewrite the equation to isolate the unknown. 8 × = 4 = (4)/(8) Step 2: Simplify the fraction. = (1)/(2) The correct value is (1)/(2) or 0.5. 5. Step 1: Rewrite the equation to isolate the unknown. (Assuming 13,8 means 13.8) 13.8 + = 28 = 28 - 13.8 Step 2: Perform the subtraction. = 14.2 The correct value is 14.2. 6. Step 1: Subtract 1 from both sides of the equation. 15 = 2 × + 1 15 - 1 = 2 × 14 = 2 × Step 2: Rewrite the equation to isolate the unknown. = (14)/(2) Step 3: Perform the division. = 7 The correct value is 7. 7. Step 1: Rewrite the equation to isolate the unknown. (2)/(3) × = 1 = 1 ÷ (2)/(3) Step 2: Multiply by the reciprocal of the fraction. = 1 × (3)/(2) = (3)/(2) The correct value is (3)/(2) or 1.5. 8. Step 1: Convert the mixed number to a decimal or improper fraction. 1(1)/(2) = 1.5 Step 2: Rewrite the equation to isolate the unknown. 1.5 + = 4 = 4 - 1.5 Step 3: Perform the subtraction. = 2.5 The correct value is 2.5 or 2(1)/(2). 9. Step 1: Take the square root of both sides of the equation. ^2 = 49 = sqrt(49) Step 2: Calculate the square root. = 7 The correct value is 7. Drop the next question.
