Final answer:
To solve this combined operation, follow the order of operations: parentheses, multiplication and division, and addition and subtraction. Simplify the expression inside the parentheses and then solve the multiplication and division. Finally, add all the results together to find the final answer.
Step-by-step explanation:
Para resolver la operación combinada dada, 40:(-8)-3.(5-16-2.5)+100=, primero, necesitamos seguir la regla de la operación matemática BODMAS/PEMDAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction), la cual nos marca el orden de las operaciones.
Primero, resolvemos el valor dentro del paréntesis, 5-16-2.5,que nos da -13.5. Luego, multiplicamos este resultado por -3, lo que nos da 40.5. A continuación, dividimos 40 entre -8, lo que da -5. Por último, sumamos estos resultados y añadimos 100. Por lo tanto, -5 + 40.5 +100 = 135.5 .
To solve this combined operation, we will follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
- First, let's simplify the expression inside the parentheses: 5 - 16 - 2.5 = -13.5.
- Now, let's solve the multiplication: 3 * -13.5 = -40.5.
- Next, let's solve the division: 40 / -8 = -5.
- Finally, let's add all the results: -5 + (-40.5) + 100 = 54.5.
Therefore, the result of the combined operation is 54.5.
