Question

Solve the expression when t = 18.

(t + 20) – (t – 6) =
A.
14


B.
26


C.
50


D.

Answer 1

To solve the expression \((t + 20) - (t - 6)\) when \(t = 18\), we will first substitute \(t\) with 18:

1. Substitute \(t\) in the expression:
\[
(18 + 20) - (18 - 6)
\]

2. Calculate \(18 + 20\) and \(18 - 6\):
\[
18 + 20 = 38
\]
\[
18 - 6 = 12
\]

3. Now, substitute these values into the expression:
\[
38 - 12
\]

4. Finally, calculate \(38 - 12\):
\[
38 - 12 = 26
\]

Thus, the final result of the expression when \(t = 18\) is \(26\).

The answer is **B. 26**.
