Q. Which expression is equivalent to 1911 -19-11 ?\newlineChoose 11 answer:\newline(A) 11+(19) -11+(19) \newline(B) 19+(11) -19+(-11) \newline(C) 19+11 19+11 \newline(D) 1119 11-19
  1. Understand the problem: Understand the problem.\newlineWe need to find an expression that is equivalent to the subtraction of 1111 from 19-19.
  2. Analyze the given choices: Analyze the given choices.\newline(A) 11+(19)-11 + (19) changes the order and signs of the numbers, which is not equivalent to 1911-19 - 11.\newline(B) 19+(11)-19 + (-11) is the same as 1911-19 - 11 because adding a negative is the same as subtracting.\newline(C) 19+1119 + 11 is adding two positive numbers, which is not equivalent to subtracting a positive number from a negative one.\newline(D) 111911 - 19 is subtracting 1919 from 1111, which is not the same as subtracting 1111 from 19-19.
  3. Choose the correct expression: Choose the correct expression.\newlineThe expression that is equivalent to 1911-19 - 11 is 19+(11)-19 + (-11) because adding a negative number is the same as subtracting that number.
