1 Question 1 of 10

Not answered

Evaluate: -8 + 15 - 6

Hint: Work from left to right: first add -8 and 15, then subtract 6.

Explanation: -8 + 15 = 7. Then 7 - 6 = 1.

2 Question 2 of 10

Not answered

Simplify: 5x - 2x + 7

Hint: Combine only the like terms with x.

Explanation: 5x - 2x = 3x. The constant 7 stays the same, so the expression is 3x + 7.

3 Question 3 of 10

Not answered

Solve for x: 3x + 4 = 22

Hint: Subtract 4 from both sides, then divide by 3.

Explanation: Subtract 4 from both sides: 3x = 18. Divide by 3, so x = 6.

4 Question 4 of 10

Not answered

What is 30% of 150?

Hint: 10% of 150 is 15. Use that to find 30%.

Not answered

A triangle has angles 55° and 70°. What is the third angle?

Hint: The angles inside a triangle add up to 180°.

Explanation: 55° + 70° = 125°. Then 180° - 125° = 55°.

8 Question 8 of 10

Not answered

What is the area of a circle with radius 5? Use π = 3.14.

Hint: Use the formula A = πr².

Explanation: A = πr² = 3.14 × 5² = 3.14 × 25 = 78.5.

9 Question 9 of 10

Not answered

A bag contains 4 yellow, 6 black, and 5 white counters. What is the probability of choosing a black counter?

Hint: Probability = number of favorable outcomes divided by total outcomes.

Explanation: There are 6 black counters and 15 counters total. The probability is 6/15.

10 Question 10 of 10
