Let's represent the unknown number as "x." The equation for "five less than a number is 15" can be written as x - 5 = 15. To solve for x, we add 5 to both sides of the equation, resulting in x = 20. Therefore, the number in question is 20.
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 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.

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.
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
x² - 15
25
They are: 5, 10 and 15
'5' & '15' are odd numbers less than 20 , and are also multiples of '5'.
