Evaluate the expression15x+4 for x=1.5

1 answer

To evaluate the expression \(15x + 4\) for \(x = 1.5\), we substitute \(1.5\) for \(x\):

\[ 15(1.5) + 4 \]

Now, calculate \(15 \times 1.5\):

\[ 15 \times 1.5 = 22.5 \]

Next, add \(4\) to \(22.5\):

\[ 22.5 + 4 = 26.5 \]

Therefore, the value of the expression \(15x + 4\) when \(x = 1.5\) is:

\[ \boxed{26.5} \]
