30. Because 10 times 3 is the same as 3 times 10 which represents 30
If ten times the number n decreased by 13 is equal to the square of the same number n increased by 3, then the value of n is either 8 or 2.
because the number are the same /example2 times 3 equals 6. 3 times 2 equals 6
if the number is the same: 2x + 3x = 13 5x = 13 x= 13/5
3x - 1 = x + 19 2x = 20 x = 10
The number is -13.

8 + y = 7 + 5y <----they are equal to the same number so are equal to each other 4y = 1 y = 0.25
The atomic mass doesn't equal to the number of protons. The number of protons plus the number of neutrons equal to the atomic weight... DAI BI!
2 times a number minus 17 plus 20 times a number minus 9 is the same as 2x - 17 + 20x - 9 = 22x - 26
30. Because 10 times 3 is the same as 3 times 10 which represents 30
because you are dividing with same signs
They are: 25 times 25 = 625 or 312.5 plus 312.5 = 625
because two plus two plus two is four and two times two is just he same thing but in multiplication.
If ten times the number n decreased by 13 is equal to the square of the same number n increased by 3, then the value of n is either 8 or 2.
