Practice Evaluating Expressions in One Variable
Practice Problems
Now, let's practice substituting values for variables. Here are seven practice problems that will allow you to show what you have learned.
-
Evaluate \(c-2\) when \(c = 7\).
-
Evaluate \(9 - \frac{8}{S}\) when \(S = 4\).
-
Evaluate \(\frac{n}{6} + 2\) when \(n = 12\).
-
Evaluate \(6h\) when \(h = 8\).
-
Evaluate \(6+x\) when \(x = 3\).
-
Evaluate \(\frac{9}{m} + 4\) when \(m = 3\).
-
Evaluate \(\frac{p}{2} -5\) when \(p = 14\).
