Question

Simplify the following expression: ((15 + 15 - (4 × 5) + 25) ÷ 5)

a) 5
b) 10
c) 15
d) 20

Answer 1

The expression ((15 + 15 - (4 × 5) + 25) ÷ 5) can be simplified by following the order of operations to get 7, which is not one of the provided answer choices.

Step-by-step explanation:

To simplify the expression ((15 + 15 - (4 × 5) + 25) ÷ 5), first we need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

1. Solve the expression within the parentheses: (15 + 15 - 20 + 25).
2. Add and subtract the numbers in the resulting expression: 15 + 15 = 30, 30 - 20 = 10, 10 + 25 = 35.
3. Finally, divide the sum by 5: 35 ÷ 5 = 7.

Thus, the simplified expression equals 7, which is not listed in the multiple choice answers provided. It appears there may have been an error in the question or the answer choices as they do not match the correct simplified result.
