# If s = 9 and t = 12 then what is 33t + s?

## Question:

If {eq}s = 9 \text{ and } t = 12 {/eq} then what is {eq}3[3t + s]? {/eq}

## Evaluating Expressions:

To evaluate a given expression at given values of the unknowns, we substitute the given values of the unknowns in the expression and then perform the arithmetic operation. For example, to evaluate {eq}5x + 3 {/eq} at {eq}x = 1 {/eq}, we need to substitute {eq}x = 1 {/eq} in the expression and simplify {eq}5(1) + 3 = 8 {/eq}.

## Answer and Explanation:

We have an expression:

• {eq}33t + s {/eq}

If {eq}s = 9 {/eq} and {eq}t = 12 {/eq}, then:

• {eq}33(12) + 9 = \boxed{\color{blue}{405}} {/eq}
