Problem 1 - College Algebra Essentials

Question

Evaluate each algebraic expression for the given value or values of the variable(s). $$7+5 x, \text { for } x=10$$

Step-by-Step Solution

Answer

The value of the expression when \(x=10\) is \(57\).

Step 1: Identify the expression and the given value

The algebraic expression here is \(7+5x\) and the value given for \(x\) is 10.

Step 2: Substitute the given value into the expression

Replace \(x\) in the expression with the given value: \(7+5(10)\)

Step 3: Application of order of operations

Solve the multiplication first, according to the BIDMAS/BODMAS rule (Brackets, Indices/Orders, Division and Multiplication, Addition and Subtraction) : \(7+50\)

Step 4: Final computation

Finally, compute the addition: \(57\)
