Question

Evaluate the expression for the given value(s) of the variable(s). $$6 b-39+c \text { when } b=15 \text { and } c=2$$

Short answer

The value of the expression \(6 b - 39 + c\) when \(b = 15\) and \(c = 2\) is 53.

Step-by-step solution

Replace Variables with Given Values

In the given expression \(6 b - 39 + c\), replace the variable 'b' with 15 and 'c' with 2, which results in the expression: \(6(15) - 39 + 2\)

Perform Operations in Correct Order

Using the order of operations BIDMAS/BODMAS (Brackets, Indices/Orders, Division/Multiplication, Addition/Subtraction), first perform the multiplication: \(6*15 = 90\). Thus, the expression becomes: \(90 - 39 + 2\)

Simplify the Expression

Continue with the addition and subtraction from left to right: \(90 - 39 + 2 = 51 + 2 = 53\)
