A.53
B.168
C.186
D.308
D?
Right.
To find the value of the expression, you need to follow the order of operations, also known as the PEMDAS acronym, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Let's solve it step by step:
7(3x18 - 10)
First, let's simplify the expression inside the parentheses:
3x18 - 10 = 54 - 10 = 44
Now, we substitute this result back into the original expression:
7(44)
Finally, multiply 7 times 44:
7(44) = 308
Therefore, the answer is D. 308.
