Adding 7 and 5 results in 12. This basic addition problem helps reinforce simple arithmetic skills.

Subtracting 4 from 9 gives 5. This problem is designed to practice basic subtraction.

Multiplying 4 by 2 results in 8. This exercise reinforces the concept of multiplication as repeated addition.

Dividing 12 by 3 gives 4. This straightforward division problem builds understanding of sharing quantities equally.

The sequence increases by 2 each time so after 6 comes 8. This problem tests the ability to recognize simple patterns.

First, add 8 and 2 to get 10, then multiply by 3 to reach 30. This question emphasizes proper use of parentheses and the order of operations.

Dividing 24 candies by 4 friends gives 6 candies each. This word problem helps practice division in a real-life context.

The area of a rectangle is found by multiplying the length by the width. Here, 7 multiplied by 5 gives an area of 35.

Subtracting 3 from both sides of the equation gives x = 7. This problem reinforces basic algebraic manipulation by isolating the variable.

Twenty percent is equal to 0.2, and multiplying 50 by 0.2 yields 10. This question helps build understanding of percentages.

First, solve the expression in the parentheses: 3 + 2 equals 5. Multiplying 4 by 5 gives 20, and subtracting 6 results in 14.

The common divisors of 18 and 24 include 1, 2, 3, and 6; the greatest of these is 6. This problem introduces basic principles of number theory.

Since a square has four equal sides, dividing the perimeter 36 by 4 gives 9. This reinforces the concept of perimeters in geometry.

Raising 2 to the power of 3 means multiplying 2 by itself three times: 2 × 2 × 2, which equals 8. This problem provides practice with exponents.

The sum of the angles in a triangle is 180°. Subtracting the given angles (35° + 65° = 100°) from 180° results in 80° for the third angle.

By adding 5 to both sides, the equation simplifies to 2x = 14. Dividing both sides by 2 gives x = 7, making it the correct solution.

Calculating 3^2 gives 9 and 4^2 gives 16. Adding these results in 25, which is the correct answer.

In an isosceles triangle, the two base angles are equal. Subtracting the vertex angle from 180° and then dividing by 2 gives (180° - 40°) / 2 = 70° for each base angle.

Average speed is calculated by dividing the total distance by the total time. Here, 60 miles divided by 1.5 hours equals 40 miles per hour.

Consecutive integers differ by one. Testing the pair 8 and 9, we see that 8 × 9 equals 72, which confirms that these are the correct integers.
