The correct answer for the order of operations in the expression 4(6+3)-24 is option D: +, -, x.
To find the value of the expression 7(3x18-10), the correct answer is option D: 308.
To simplify the expression 4(3+2)+2(16/4), the correct answer is option B: 44.
To simplify the expression 451+5x5, the correct answer is option C: 481.
For the first question, we need to follow the correct order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right). To evaluate the expression 4(6+3)-24, we start by simplifying the expression in the parentheses: 6+3 = 9. Then, we perform the multiplication: 4 x 9 = 36. Finally, we perform the subtraction: 36 - 24 = 12. Based on the choices given, we find that the correct order of operations is B. x, +, -.
For the second question, we need to evaluate the expression 7(3x18-10). Similarly, we follow the order of operations. First, we simplify the expression in the parentheses: 3 x 18 - 10 = 54 - 10 = 44. Lastly, we perform the multiplication: 7 x 44 = 308. Therefore, the correct answer is D.
In the third question, we are asked to simplify the expression 4(3+2)+2(16/4). Following the order of operations, we first simplify the expressions in the parentheses: 3+2 = 5 and 16/4 = 4. Then, we perform the multiplications: 4 x 5 = 20 and 2 x 4 = 8. Finally, we perform the addition: 20 + 8 = 28. Therefore, the correct answer is D.
Lastly, for the fourth question, we need to simplify the expression 451+5x5. Again, we follow the order of operations. We perform the multiplication: 5 x 5 = 25. Then, we perform the addition: 451 + 25 = 476. Thus, the correct answer is B.
