1 answer

To simplify the expression \(21 + 49 ÷ 7 + 1\), we need to follow the order of operations (PEMDAS/BODMAS):

  1. Division comes first. \[ 49 ÷ 7 = 7 \]

  2. Now substitute back into the expression: \[ 21 + 7 + 1 \]

  3. Perform the addition from left to right: \[ 21 + 7 = 28 \] \[ 28 + 1 = 29 \]

So the simplified expression is \(29\).

Thus, the answer is A. 29.
