50x+75=65x
Now divide
15x=75/15
Your Solution
<span>x= 5</span>
You are solving the problem 4 x 3. This is really another way to say "3 groups of four."<span>You can think of this as repeated addition, where the number four will be repeated 3 times. But you are adding the number the amount of times you want to multiply it by.</span>
In this question, there are 10 digit phone number which was divided into 3-3-4 digits. Every first digit of the division should be 2-9 which mean only 8 possibilities. The other digits would be 0-9 which mean 10 possibilities. Then the calculation would be:
8*10*10 * 8*10*10 * 8*10*10*10 = 8^3 * 10*7= 512 * 10^7= 5.12 * 10^9
If you convert <span>400,000,000 into the scientific form it will become 4* 10^8. Since 5.12*10^9 > 4 * 10^8, then it is clear that the number should be enough</span>
