10 - x + y ÷ 2; x = 5 & y = 2
Answer (2)
When substituting x = 5 and y = 2 into the expression 10 − x + 2 y , the value simplifies step by step to 6 . This is achieved by performing division, subtraction, and addition in that order. Therefore, the final answer is 6 .
;
Substitute the given values x = 5 and y = 2 into the expression.
Perform the division: 2" , d i v "2 = 1 .
Perform the subtraction: 10 − 5 = 5 .
Perform the addition: 5 + 1 = 6 . The final answer is 6 .
Explanation
Understanding the Problem We are given the expression 10 − x + y " , d i v "2 and the values x = 5 and y = 2 . We need to substitute these values into the expression and evaluate it.
Substitution First, substitute x = 5 and y = 2 into the expression: 10 − 5 + 2" , d i v "2
Performing Division Next, perform the division operation. Since 2" , d i v "2 = 1 , the expression becomes: 10 − 5 + 1
Performing Subtraction Now, perform the subtraction operation: 10 − 5 = 5 . So the expression becomes: 5 + 1
Performing Addition Finally, perform the addition operation: 5 + 1 = 6 . Therefore, the value of the expression is 6.
Final Answer The value of the expression 10 − x + y " , d i v "2 when x = 5 and y = 2 is 6.
Examples
In programming, you might use an expression like this to calculate a score based on certain parameters. For example, '10' could be a base score, 'x' could be a penalty, and 'y' could be a bonus. Understanding how to evaluate such expressions is crucial for writing accurate and reliable code. This type of calculation can also be used in simple budgeting, where you start with an initial amount, subtract expenses, and add any earnings.
