ACT Exams Math Easy 1

Correct answer: 6
Explanation: To solve for x, we need to isolate it on one side of the equation. Subtracting 7 from both sides gives us 3x = 15. Dividing both sides by 3 yields x = 5.

Correct answer: 8
Explanation: The square root of a number is a value that, when multiplied by itself, gives the original number. Since 8 * 8 = 64, the square root of 64 is 8.

Correct answer: 34 units
Explanation: The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the perimeter is 2 * (12 + 5) = 2 * 17 = 34 units.

Correct answer: 120
Explanation: The factorial of a number is the product of all positive integers from 1 to that number. In this case, 5! = 5 * 4 * 3 * 2 * 1 = 120.

Correct answer:  2
Explanation: To solve for x, we subtract 4 from both sides of the equation, resulting in 3x = 6. Dividing both sides by 3 gives us x = 2.

Correct answer: 64 square units
Explanation: The area of a square is calculated by multiplying the length of one side by itself. In this case, the area is 8 * 8 = 64 square units.

Correct answer:  3/10
Explanation: To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 10. The sum is (4/10) + (1/10) = 5/10, which simplifies to 1/2 or 0.5.

Correct answer:  4 units
Explanation: According to the Pythagorean theorem, in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, 6^2 + x^2 = 10^2, which simplifies to 36 + x^2 = 100. Solving for x, we find x = 4.

Correct answer:  4
Explanation: To solve for y, we subtract 3 from both sides of the equation, giving us 2y = 6. Dividing both sides by 2 yields y = 3.

Correct answer: 1/4
Explanation: To convert a decimal to a fraction, we place the decimal value over a power of 10. In this case, 0.25 can be written as 25/100. Simplifying this fraction gives us 1/4.
