Given the values: a=2, b=5, c=3. Step 1: Evaluate the first expression, a+b. Substitute the given values into the expression: a+b = 2+5 = 7 The student's answer of 7 is correct. Step 2: Evaluate the second expression, 3c. Substitute the given value into the expression: 3c = 3 × 3 = 9 The student's answer of 9 is correct. Step 3: Evaluate the third expression, b-a. Substitute the given values into the expression: b-a = 5-2 = 3 The student's answer of 3 is correct. Step 4: Evaluate the fourth expression, 4a+c. Substitute the given values into the expression: 4a+c = 4 × 2 + 3 Perform the multiplication first: 4 × 2 + 3 = 8 + 3 = 11 The student's answer of 10 is incorrect. The correct answer is 11. Here are the evaluated expressions: 1. a+b = 7 (Student's answer: Correct) 2. 3c = 9 (Student's answer: Correct) 3. b-a = 3 (Student's answer: Correct) 4. 4a+c = 11 (Student's answer: Incorrect, should be 11) Got more?
