Question

Evaluate the expression for x = 1.9.

Write your answer as a decimal or whole number.

10.7x − 33.7 + 26x =

Answer 1

To evaluate the expression \(10.7x - 33.7 + 26x\) for \(x = 1.9\), we first substitute \(x\) with \(1.9\):

\[
10.7(1.9) - 33.7 + 26(1.9)
\]

Now, calculate \(10.7(1.9)\):

\[
10.7 \times 1.9 = 20.33
\]

Next, calculate \(26(1.9)\):

\[
26 \times 1.9 = 49.4
\]

Now, substitute these values back into the expression:

\[
20.33 - 33.7 + 49.4
\]

Perform the subtraction:

\[
20.33 - 33.7 = -13.37
\]

Now add \(49.4\):

\[
-13.37 + 49.4 = 36.03
\]

So, the final value of the expression when \(x = 1.9\) is:

\[
\boxed{36.03}
\]
