15-(m+p); m=-5 & p=-10

To solve the expression 15 − ( m + p ) with m = − 5 and p = − 10 , we first simplify ( − 5 ) + ( − 10 ) = − 15 and substitute it back, resulting in 15 + 15 = 30 . The final answer is 30 .

Explanation

Understanding the Problem We are given the expression 15 − ( m + p ) and the values m = − 5 and p = − 10 . We need to substitute these values into the expression and simplify to find the result.

Substituting the Values First, let's substitute the given values of m and p into the expression: 15 − ( m + p ) = 15 − (( − 5 ) + ( − 10 ))

Simplifying Inside Parentheses Now, let's simplify the expression inside the parentheses: ( − 5 ) + ( − 10 ) = − 15

Substituting Back Substitute this result back into the original expression: 15 − ( − 15 )

Simplifying the Expression Finally, simplify the expression: 15 − ( − 15 ) = 15 + 15 = 30

Final Answer Therefore, the value of the expression 15 − ( m + p ) when m = − 5 and p = − 10 is 30.


Examples
Understanding how to substitute values into expressions is crucial in many real-world scenarios. For example, if you're calculating the profit of a business, you might have an expression that depends on the number of items sold and the cost per item. By substituting the actual values into the expression, you can quickly determine the profit. Similarly, in physics, you might use formulas that require substituting values for variables like velocity and time to calculate distance. This skill is also useful in everyday situations, such as calculating the total cost of items on sale after applying discounts.
