Problem 1
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
Verified Answer
The evaluated expression is 57.
1Step 1: Substitute the given value
Firstly, we are given \(x = 10\) and it is asked to evaluate the algebraic expression which is \(7+5x\). So, substitute \(x = 10\) into the expression. This gives us \(7 + 5*10\).
2Step 2: Evaluate the algebraic expression
Now evaluate the given expression. According to the operator precedence in mathematics (BODMAS rule), multiplication is done before addition. So, \(5*10 = 50\). Then add \(7 + 50\) to get \(57\).
3Step 3: Conclusion
The value of the algebraic expression \(7+5x\) for \(x=10\) is \(57\) .
