Question

evaluate the expression when (c = - 5) and (y = 5).
(8y - c)

Explanation:

Step1: Substitute values

Substitute $c = - 5$ and $y = 5$ into $8y - c$. We get $8\times5-(-5)$.

Step2: Calculate multiplication

First, calculate $8\times5 = 40$. The expression becomes $40-(-5)$.

Step3: Handle subtraction of negative number

Subtracting a negative number is the same as adding a positive number. So $40-(-5)=40 + 5$.

Step4: Calculate final result

$40+5=45$.

Answer:

$45$
