15-5 = 10
Five
15 less than 7 times a number is:15-7n
Let's denote the number as x. The quotient of the number and 4 is x/4. Five less than this quotient would be (x/4) - 5. The equation we have is (x/4) - 5 = 15. By solving this equation, we find that x = 80.
yes
15-5 = 10
Five
x - 5 = 15Therefore 15 + 5 = xx = 20
15 − 5 = 10Therefore the number is 15
15 less than 7 times a number is:15-7n
That means that the sum of the number's factors, less than the number itself, is less than the number in question - in this case, if you add the factors of 15 (except 15 itself, which is also a factor of 15), you get a total that is less than 15.

Six times a number minus five is less than twice the number plus ten. 6 * n - 5 < 2 * n + 10 6n - 5 < 2n + 10 4n - 5 < 10 4n < 15 n < 15/4 This statement will hold true for all n < 15/4
No, however there are even numbers less than 15. An even number is any number that can be divided by two evenly, so it can be greater than 15 too.
x² - 15
They are: 5, 10 and 15
