I can't make this work. Please help?
Insert parentheses when necessary to make the number sentence true. 5-3x4/6+4=-9
Thank you!
5 - {3x[(4/6)+4]}
= 5 - [3x(14/3)]
= 5 - 14 = -9
Tricky one! You need to use embedded parentheses (brackets) twice.
To solve this problem and make the number sentence true, we need to insert parentheses to clarify the order of operations. The order of operations, also known as PEMDAS, stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Let's break down the given number sentence and insert parentheses to clarify the operations:
5 - 3 × 4 ÷ 6 + 4 = -9
First, we will evaluate the multiplication and division from left to right:
5 - (3 × 4 ÷ 6) + 4 = -9
Next, we will solve the multiplication and division inside the parentheses:
5 - (12 ÷ 6) + 4 = -9
Now, we can perform the division:
5 - (2) + 4 = -9
Lastly, we calculate the addition and subtraction from left to right:
(5 - 2) + 4 = -9
3 + 4 = -9
7 = -9
Since 7 is not equal to -9, we can conclude that there is no way to insert parentheses to make the number sentence true.
I hope this explanation helps! Let me know if you have any further questions.
