1. QuestionMultiple choice

If x + 8 = 21, what is x?

Please select an answer first.

Correct answer: A

The correct answer is 13.

  1. Read the Idaho math task: Identify the quantities, operation, representation, or relationship the question asks you to examine.
  2. Show the reasoning: Subtract 8 from both sides: x = 21 − 8 = 13.
  3. Check the result: Confirm that the answer is reasonable, uses the correct units, and matches the problem conditions.

Subtract 8 from both sides: x = 21 − 8 = 13.

2. QuestionMultiple choice

If 5n = 45, what is n?

Please select an answer first.

Correct answer: B

The correct answer is 9.

  1. Read the Idaho math task: Identify the quantities, operation, representation, or relationship the question asks you to examine.
  2. Show the reasoning: Divide both sides by 5: n = 45 ÷ 5 = 9.
  3. Check the result: Confirm that the answer is reasonable, uses the correct units, and matches the problem conditions.

Divide both sides by 5: n = 45 ÷ 5 = 9.

3. QuestionMultiple choice

Which expression represents 4 more than 3 times y?

Please select an answer first.

Correct answer: C

The correct answer is 3y + 4.

  1. Read the Idaho math task: Identify the quantities, operation, representation, or relationship the question asks you to examine.
  2. Show the reasoning: Three times y is 3y, and 4 more gives 3y + 4.
  3. Check the result: Confirm that the answer is reasonable, uses the correct units, and matches the problem conditions.

Three times y is 3y, and 4 more gives 3y + 4.

4. QuestionMultiple choice

What is the value of 2a + 5 when a = 6?

Please select an answer first.

Correct answer: D

The correct answer is 17.

  1. Read the Idaho math task: Identify the quantities, operation, representation, or relationship the question asks you to examine.
  2. Show the reasoning: Substitute 6 for a: 2 × 6 + 5 = 17.
  3. Check the result: Confirm that the answer is reasonable, uses the correct units, and matches the problem conditions.

Substitute 6 for a: 2 × 6 + 5 = 17.

5. QuestionMultiple choice

A pattern begins 4, 7, 10, 13. What is the next number?

Please select an answer first.

Correct answer: A

The correct answer is 16.

  1. Read the Idaho math task: Identify the quantities, operation, representation, or relationship the question asks you to examine.
  2. Show the reasoning: The pattern increases by 3 each time, so 13 + 3 = 16.
  3. Check the result: Confirm that the answer is reasonable, uses the correct units, and matches the problem conditions.

The pattern increases by 3 each time, so 13 + 3 = 16.

6. QuestionMultiple choice

Which equation represents a total cost of 6 dollars per notebook for n notebooks plus a 4-dollar delivery fee?

Please select an answer first.

Correct answer: B

The correct answer is c = 6n + 4.

  1. Read the Idaho math task: Identify the quantities, operation, representation, or relationship the question asks you to examine.
  2. Show the reasoning: The notebook cost is 6n and the fixed delivery fee is 4.
  3. Check the result: Confirm that the answer is reasonable, uses the correct units, and matches the problem conditions.

The notebook cost is 6n and the fixed delivery fee is 4.

7. QuestionMultiple choice

What is the slope of a line that rises 12 units while running 3 units?

Please select an answer first.

Correct answer: C

The correct answer is 4.

  1. Read the Idaho math task: Identify the quantities, operation, representation, or relationship the question asks you to examine.
  2. Show the reasoning: Slope equals rise divided by run: 12 ÷ 3 = 4.
  3. Check the result: Confirm that the answer is reasonable, uses the correct units, and matches the problem conditions.

Slope equals rise divided by run: 12 ÷ 3 = 4.

8. QuestionMultiple choice

If y = 2x + 1, what is y when x = 5?

Please select an answer first.

Correct answer: D

The correct answer is 11.

  1. Read the Idaho math task: Identify the quantities, operation, representation, or relationship the question asks you to examine.
  2. Show the reasoning: Substitute 5: y = 2 × 5 + 1 = 11.
  3. Check the result: Confirm that the answer is reasonable, uses the correct units, and matches the problem conditions.

Substitute 5: y = 2 × 5 + 1 = 11.

9. QuestionMultiple choice

Which value makes the inequality n > 8 true?

Please select an answer first.

Correct answer: A

The correct answer is 11.

  1. Read the Idaho math task: Identify the quantities, operation, representation, or relationship the question asks you to examine.
  2. Show the reasoning: Eleven is greater than 8, so it satisfies n > 8.
  3. Check the result: Confirm that the answer is reasonable, uses the correct units, and matches the problem conditions.

Eleven is greater than 8, so it satisfies n > 8.

10. QuestionMultiple choice

A table shows x-values 1, 2, 3 and y-values 5, 8, 11. What rule connects x and y?

Please select an answer first.

Correct answer: B

The correct answer is y = 3x + 2.

  1. Read the Idaho math task: Identify the quantities, operation, representation, or relationship the question asks you to examine.
  2. Show the reasoning: Each y-value is 3 times x plus 2: 5, 8, and 11.
  3. Check the result: Confirm that the answer is reasonable, uses the correct units, and matches the problem conditions.

Each y-value is 3 times x plus 2: 5, 8, and 11.
