What is the value of x if 4x + 3 = 23?

  1. 4
  2. 6
  3. 5
  4. 3

Answer(s): C

Explanation:

Try plugging each of the given choices as x in the expression 4x + 3 and see which one will give the value of 23. If we take x = 5, we have 5x4 equals 20, and 20 + 3 equals 23. Clearly, 5 is the correct answer.
Another method would be to solve algebraically: 4x + 3 = 23; isolate the term with the x variable: 4x = 23 − 3 = 20; we then have: 4x = 20; divide both sides of the equation by 4 to get the value of x: 4x/4=20/4; this gives us the value of x:x = 5.



What is 104?

  1. 10,000
  2. 10
  3. 100
  4. 100,000

Answer(s): A

The expression 104 means that the base, 10, is raised to the power of 4 or multiplied by itself 4 times. Thus, 10 × 10 × 10 × 10 = 10,000.



5 is what percentage of 40?

  1. 12.5%
  2. 15%
  3. 10.5%
  4. 25%

Answer(s): A

Explanation:

Remember always that percentage is a mathematical expression for “a part of a whole” or per 100. For problems such as this, the following formula is very useful: part/whole=percentage/100. Since we want to know what percentage of 40 is 5, simply substitute the given numbers to the formula, and so we have: 5/40=percentage/100. 0.125 × 100=percentage. The correct answer is 12.5.



What is the decimal equivalent of 3/8?

  1. 0.625

Explanation:

To get the decimal equivalent of a fraction, simply divide the numerator by the denominator. For the fraction 3/8, divide 3 by 8 to get 0.375, the correct answer.
