Answer:
Probability is : 1/30240= 0.000033068
Step-by-step explanation:
You pick 5 digits (0-9) at random without replacement, and write them in the order picked.
The probability that you have written the first 5 digits of your phone number is -
As there are no repeats, the choice to choose from decreases at each step making it 10,9,8,7,6.

2х3+10х+2у2-х-у=2х3+9х+2у2-у=2*3in3+9*3+2*5in2-5=2*27+27+2*25-5=54+27+50-5=126
Write everything on one side
2/3x-y+1=0
multiply by 3
2x-3y+3=0
I hope this is what you're looking for
16 because 36 divided by 9 is 4 so you have to multiply the 4 x 4
If you square 3, you get 9, and if you "take the square root of 9", you get 3
