Let's denote the number as \( x \). According to the problem, we can set up the equation:
\[
\frac{1}{2}x - 5 = 20
\]
Now, let's solve for \( x \).
1. Add 5 to both sides:
\[
\frac{1}{2}x = 20 + 5
\]
\[
\frac{1}{2}x = 25
\]
2. Multiply both sides by 2 to solve for \( x \):
\[
x = 25 \times 2
\]
\[
x = 50
\]
Thus, the number is \( 50 \). The correct answer is:
**50**
\[
\frac{1}{2}x - 5 = 20
\]
Now, let's solve for \( x \).
1. Add 5 to both sides:
\[
\frac{1}{2}x = 20 + 5
\]
\[
\frac{1}{2}x = 25
\]
2. Multiply both sides by 2 to solve for \( x \):
\[
x = 25 \times 2
\]
\[
x = 50
\]
Thus, the number is \( 50 \). The correct answer is:
**50**
