x < 7
Suppose the number is x. Then the inequality is: x - 7 < 5 which is equivalent to x < 12

The prime numbers less than 10 are 2, 3, 5, and 7. There are several possibilities for the answer to this question since we do not know how many prime factors there are. We know that all of them are less than 10 and they do not repeat. However, we do not know whether the prime factors are all of the the prime numbers less than 10 or a selection of them. Possibilities: 2 x 3 = 6 2 x 5 = 10 2 x 7 = 14 3 x 5 = 15 3 x 7 = 21 5 x 7 = 35 2 x 3 x 5 = 30 2 x 3 x 7 = 42 2 x 5 x 7 = 70 3 x 5 x 7 = 105 2 x 3 x 5 x 7 = 210
Let the number be x Twice a number means 2x 7 less than twice a number means 2x-7
x-7
* == == what are the values of square root of x is less than 7 ? ----
6x<42 x<7 x must be less than 7
x<7
Such a number cannot exist sine the relationship "less than" is transitive. That is: 7 < 8 Then, if x < 7 it follows that x < 8.
x < 7
(7 x 7 x 7) - 19 = 324
7
x is less than or equal to 6
2 times 3 = 6 which is less than 7 or 1 times 3 = 3 which is less than 7
7cos(x)=3sin(x) 7=3[sin(x)/cos(x)] 7=3tan(x) 7/3=tan(x) x=66.8, 246.8
This is called an inequality. If x squared is greater than or equal to 49, then x is plus or minus 7 or greater than plus 7 or less than - 7.
