What is the value of the expression below

Question

10, z, plus, 5 10z+5 when z, equals, 5z=5?

Answer 1

To evaluate the expression \(10z + 5\) when \(z = 5\), we substitute \(5\) for \(z\) in the expression.

Starting with the expression:

\[ 10z + 5 \]

Substituting \(z = 5\):

\[ 10(5) + 5 \]

Now, we calculate \(10(5)\):

\[ 10 \times 5 = 50 \]

Now, we add \(5\) to this result:

\[ 50 + 5 = 55 \]

Thus, the value of the expression \(10z + 5\) when \(z = 5\) is

\[ \boxed{55} \]
