Question

find the value of the expression 11.5 · u for u = 1.

Explanation:

Step1: Substitute u = 1 into the expression

We have the expression \(11.5 \cdot u\), and we substitute \(u = 1\) into it. So the expression becomes \(11.5 \cdot 1\).

Step2: Calculate the product

Multiplying \(11.5\) by \(1\) gives \(11.5\) (since any number multiplied by 1 is the number itself).

Answer:

\(11.5\)
