He was wrong, you cannot make 10 coins by adding 32 coins to 28 coins. If you want to obtain 10 coins from 32 coins and 28 coins, you can subtract 28 coins from 32 coins.
This can be illustrated as follows:
32-28=10
Answer:
Step-by-step explanation:
<u>Subtract the values:</u>
- 19 1/12 - 8 5/12 =
- 18 13/12 - 8 5/12 =
- 18 - 8 + 13/12 - 5/12 =
- 10 + 8/12 =
- 10 8/12 =
- 10 2/3 in
Answer:
Initially, <em>there were 50 memes</em>.
Step-by-step explanation:
It is given that the number doubles daily.
Let the initial number = a
On 2nd day, the number = 2a
On 3rd day, the number = 2 2a
On 4th day, the number = 2 2 2a
and so on..
If we look closely, it is a Geometric Progression with
First term = a and
The common ratio, r = 2
Also, it is given that, 12th term:
nth term of a GP is given as:
So,
Hence, the answer is, the <em>initial number is 50</em>.

Answer:
3*5^2
Step-by-step explanation:
75 is divisible by 3
