Evaluate the expression when x = 2.5 and y = 6

Question

5xy

Answer 1

To evaluate the expression \(5xy\) when \(x = 2.5\) and \(y = 6\), you can follow these steps:

1. Substitute \(x = 2.5\) and \(y = 6\) into the expression:
\[
5xy = 5 \times 2.5 \times 6
\]

2. First, multiply \(2.5\) by \(6\):
\[
2.5 \times 6 = 15
\]

3. Then, multiply the result by \(5\):
\[
5 \times 15 = 75
\]

So, the value of the expression \(5xy\) when \(x = 2.5\) and \(y = 6\) is \(75\).
