Evaluate the expression when a=8 and b=6   b+5a

To evaluate the expression \( b + 5a \) when \( a = 8 \) and \( b = 6 \), follow these steps:

1. Substitute the value of \( a = 8 \) into the expression.
2. Substitute the value of \( b = 6 \) into the expression.
3. Perform the multiplication and addition.

Let's do it:

\[
b + 5a = 6 + 5(8)
\]

\[
= 6 + 40
\]

\[
= 46
\]

So, the expression evaluates to **46**.

Here are 5 related questions:

1. What is the value of \( b + 5a \) if \( a = 3 \) and \( b = 7 \)?
2. How does changing the value of \( a \) affect the result of the expression \( b + 5a \)?
3. What happens if both \( a \) and \( b \) are negative in the expression \( b + 5a \)?
4. Can you express the formula \( b + 5a \) in terms of a different variable by substitution?
5. How would the expression change if instead of adding \( b \), you subtracted \( b \)?

**Tip:** When substituting values into expressions, always follow the order of operations: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).
