<h2><em>
If digits can be repeated: 36</em></h2><h2><em>
If the digit can not be repeated: 30</em></h2>
Step-by-step explanation:
<em>If digits can be repeated:</em>
On the first and second place we have 6 digits to choose from.
Therefore we have 6 · 6 = 36 two-digit numbers.
<em>If the digit can not be repeated:</em>
On the first place we have 6 digits to choose from and on the second place we have 5 digits to choose from.
Therefore we have 6 · 5 = 30 two-digit numbers.

Answer:
a = 21
Step-by-step explanation:
Step 1: Write equation
6(1/2a - 3) = 1/4(12 + 8a)
Step 2: Solve for <em>a</em>
- Distribute: 3a - 18 = 3 + 2a
- Subtract 2a on both sides: a - 18 = 3
- Add 18 to both sides: a = 21
