What value is equivalent to 8 · 9 − 2 · 5?
Responses
A 82
B 280
C 350
D 62
E 52
The correct answer is D) 62.
Using the order of operations (PEMDAS), we first perform the multiplication:
8 · 9 = 72
2 · 5 = 10
Then, we subtract the result of 2 · 5 from the result of 8 · 9:
72 - 10 = 62
Therefore, 8 · 9 − 2 · 5 is equivalent to 62.
To solve this expression, you need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
The expression 8 · 9 − 2 · 5 can be simplified as follows:
Step 1: Perform the multiplication operations from left to right:
8 · 9 = 72
2 · 5 = 10
Now, the expression becomes:
72 - 10
Step 2: Perform the subtraction operation:
72 - 10 = 62
Therefore, the value equivalent to 8 · 9 − 2 · 5 is 62. Hence, the answer is option D.
To find the value that is equivalent to 8 · 9 - 2 · 5, we need to follow the order of operations (also known as PEMDAS: Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).
First, let's simplify the multiplication operations:
8 · 9 - 2 · 5 becomes 72 - 2 · 5.
Next, we perform the remaining multiplication operation:
72 - 2 · 5 equals 72 - 10.
Lastly, we perform the subtraction operation:
72 - 10 equals 62.
Therefore, the value that is equivalent to 8 · 9 - 2 · 5 is 62.
The correct answer is option D: 62.
