The expression 8 · 9 − 2 · 5 can be simplified using the order of operations (PEMDAS) by performing the multiplication before the subtraction:
8 · 9 − 2 · 5 = 72 - 10 = 62
Therefore, the value equivalent to 8 · 9 − 2 · 5 is 62.
The answer is B) 62.
To find the value equivalent to 8 · 9 - 2 · 5, follow the order of operations, which states that multiplication and division should be performed before addition and subtraction.
First, perform the multiplication:
8 · 9 = 72
2 · 5 = 10
Now subtract:
72 - 10 = 62
Therefore, the value equivalent to 8 · 9 - 2 · 5 is 62.
Therefore, the answer is B) 62.
To find the value equivalent to the expression 8 · 9 − 2 · 5, we need to follow the order of operations, which is often remembered as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Multiplication and division are typically performed from left to right.
Let's break down the expression step by step:
1. Start with the multiplication operation: 8 · 9 = 72.
- You can multiply 8 and 9 to get the product of 72.
2. Move on to the next multiplication operation: 2 · 5 = 10.
- Multiply 2 and 5 to get the product of 10.
3. Next, subtract the result of the second multiplication from the result of the first multiplication: 72 − 10 = 62.
- Subtract 10 from 72 to get the difference of 62.
Therefore, the value equivalent to 8 · 9 − 2 · 5 is 62.
So, the correct answer is B: 62.
