1. QuestionMultiple choice

If x + 9 = 25, what is x?

Please select an answer first.

Correct answer: A

The correct answer is 16.

  1. Read the IAR math task: Identify the quantities, operation, representation, or relationship the problem asks you to use.
  2. Show the reasoning: Subtract 9 from both sides: x = 25 − 9 = 16.
  3. Check the result: Confirm that the answer is reasonable and that units, labels, and conditions are included.

Subtract 9 from both sides: x = 25 − 9 = 16.

2. QuestionMultiple choice

If 4n = 36, what is n?

Please select an answer first.

Correct answer: B

The correct answer is 9.

  1. Read the IAR math task: Identify the quantities, operation, representation, or relationship the problem asks you to use.
  2. Show the reasoning: Divide both sides by 4: n = 36 ÷ 4 = 9.
  3. Check the result: Confirm that the answer is reasonable and that units, labels, and conditions are included.

Divide both sides by 4: n = 36 ÷ 4 = 9.

3. QuestionMultiple choice

Which expression represents 5 less than 2 times y?

Please select an answer first.

Correct answer: C

The correct answer is 2y − 5.

  1. Read the IAR math task: Identify the quantities, operation, representation, or relationship the problem asks you to use.
  2. Show the reasoning: Two times y is 2y, and 5 less gives 2y − 5.
  3. Check the result: Confirm that the answer is reasonable and that units, labels, and conditions are included.

Two times y is 2y, and 5 less gives 2y − 5.

4. QuestionMultiple choice

What is the value of 3a + 4 when a = 5?

Please select an answer first.

Correct answer: D

The correct answer is 19.

  1. Read the IAR math task: Identify the quantities, operation, representation, or relationship the problem asks you to use.
  2. Show the reasoning: Substitute 5 for a: 3 × 5 + 4 = 19.
  3. Check the result: Confirm that the answer is reasonable and that units, labels, and conditions are included.

Substitute 5 for a: 3 × 5 + 4 = 19.

5. QuestionMultiple choice

A pattern begins 6, 10, 14, 18. What is the next number?

Please select an answer first.

Correct answer: A

The correct answer is 22.

  1. Read the IAR math task: Identify the quantities, operation, representation, or relationship the problem asks you to use.
  2. Show the reasoning: The pattern increases by 4, so 18 + 4 = 22.
  3. Check the result: Confirm that the answer is reasonable and that units, labels, and conditions are included.

The pattern increases by 4, so 18 + 4 = 22.

6. QuestionMultiple choice

Which equation represents a total cost of 7 dollars per ticket for t tickets plus a 3-dollar fee?

Please select an answer first.

Correct answer: B

The correct answer is c = 7t + 3.

  1. Read the IAR math task: Identify the quantities, operation, representation, or relationship the problem asks you to use.
  2. Show the reasoning: The ticket cost is 7t and the fixed fee is 3.
  3. Check the result: Confirm that the answer is reasonable and that units, labels, and conditions are included.

The ticket cost is 7t and the fixed fee is 3.

7. QuestionMultiple choice

What is the slope of a line that rises 15 units while running 5 units?

Please select an answer first.

Correct answer: C

The correct answer is 3.

  1. Read the IAR math task: Identify the quantities, operation, representation, or relationship the problem asks you to use.
  2. Show the reasoning: Slope equals rise divided by run: 15 ÷ 5 = 3.
  3. Check the result: Confirm that the answer is reasonable and that units, labels, and conditions are included.

Slope equals rise divided by run: 15 ÷ 5 = 3.

8. QuestionMultiple choice

If y = 3x − 2, what is y when x = 4?

Please select an answer first.

Correct answer: D

The correct answer is 10.

  1. Read the IAR math task: Identify the quantities, operation, representation, or relationship the problem asks you to use.
  2. Show the reasoning: Substitute 4: y = 3 × 4 − 2 = 10.
  3. Check the result: Confirm that the answer is reasonable and that units, labels, and conditions are included.

Substitute 4: y = 3 × 4 − 2 = 10.

9. QuestionMultiple choice

Which value makes the inequality n ≤ 7 true?

Please select an answer first.

Correct answer: A

The correct answer is 5.

  1. Read the IAR math task: Identify the quantities, operation, representation, or relationship the problem asks you to use.
  2. Show the reasoning: Five is less than or equal to 7, so it satisfies the inequality.
  3. Check the result: Confirm that the answer is reasonable and that units, labels, and conditions are included.

Five is less than or equal to 7, so it satisfies the inequality.

10. QuestionMultiple choice

A table shows x-values 1, 2, 3 and y-values 4, 7, 10. What rule connects x and y?

Please select an answer first.

Correct answer: B

The correct answer is y = 3x + 1.

  1. Read the IAR math task: Identify the quantities, operation, representation, or relationship the problem asks you to use.
  2. Show the reasoning: Each y-value is 3 times x plus 1.
  3. Check the result: Confirm that the answer is reasonable and that units, labels, and conditions are included.

Each y-value is 3 times x plus 1.
