    The sum of three times x and 10 is 13.

  • 3x + 10 = 13
  • 3x - 10 = 13
  • 3x + 13 = 10
  • none of these

  • 2. 
    Write the following statement in the form of an equation:
    If you subtract 3 from 6 times a number, you get 9

  • 3x - 6 = 9
  • 6x - 3 = 9
  • 6x + 3 = 9
  • 3x + 6 = 9

  • 3. 
    Write the following statement in the form of an equation:
    One fourth of n is 3 more than 2

  • \(\frac { n }{ 4 } \) - 2 = 3
  • \(\frac { n }{ 4 } \) + 2 = 3
  • \(\frac { n }{ 2 } \) - 4 = 3
  • \(\frac { n }{ 2 } \) + 4 = 3

  • 4. 
    Write the following statement in the form of an equation:
    One third of a number plus 2 is 3

  • \(\frac { m }{ 3 } \) - 2 = 3
  • \(\frac { m }{ 3 } \) + 2 = 3
  • \(\frac { m }{ 2 } \) - 3 = 3
  • \(\frac { m }{ 2 } \) + 3 = 3

  • 5. 
    Write the following statement in the form of an equation:
    Taking away 5 from x gives 10

  • x - 5 = 10
  • x + 5 = 10
