Write each verbal expression as an algebraic expression

Question

1. four times the sum of a number and five
2. ten less than three times some number
3. one-half of a number decreased by eleven
4. three more than the quotient of a number and two

Answer 1

PEMDAS, Parentheses, Exponentiation, Multiplication or Division, Addition or Subtraction, in that order, will be used. X will be the unknown number in all cases. Parentheses will be used if context warrants.

1. four times the sum of a number and five ==> 4*(X+5)
2. ten less than three times some number ==> 3*X - 10
3. one-half of a number decreased by eleven ==> X/2 - 11
4. three more than the quotient of a number and two ==> (3*X) / 2
