(x - 8)/(x + 28) = 2/5
Cross-multiply: 5x - 40 = 2x + 56
Subtract 2x from each side: 3x - 40 = 56
Add 40 to each side: 3x = 96
Divide each side by 3: x = 32
Check: 24/60 = 2/5? Yes, job done.
A number cannot be "less than but more than 40".
The number that 30 is ten less than is 40. Half that is 20. So the question becomes "what number is as much more than 10 is less than 20". This is gobbledygook, but if I rephrase to say "what number is as much more than 10 than 10 is less than 20", then since10 is less than 20 by 10, I guess 20.

Either a number greater than 250 but less than 255 Or a number less than 250 but more than or equal to 245
Zero is more than, not less than the number negative 1.
ok i need help with my homework its fking hard as hell
It is a ratio of 5:13
A mile is more than a kilometer. The conversion ratio is about 1:1.6a mile is more.
There are a few numbers that are less than 19 and have more than 4 factors. The number 10 is less than 19 and has more than four factors.
The only number that's neither more nor less than 50 is 50.
A number cannot be "less than but more than 40".
There is no such number.
As N approaches infinity the ratio of squares less than N to numbers with 4 factors less than N approaches 0. This means that in the customary way of defining it, the ratio you're interested in is 0 (although that should be taken with a grain of salt - it certainly doesn't mean that there are 0 square numbers). The number of squares less than N is approximately √N. Rather than calculating the ratio we're interested in, we're going to calculate a calculate a ratio guaranteed to be greater: the ratio of squares to numbers that are twice a prime number (which are some, but not all, of the numbers with 4 factors). There are approximately N/ln N prime numbers less than N, by the prime number theorem. So there are N/(2 ln N/2) prime numbers less than N/2, which can be doubled to get a number less than N that's twice a prime number. The ratio is therefore √N(2 ln N/2)/N, which is O(ln N/√N). √N grows much faster than ln N, and in the limit this ratio will get close to zero. So the ratio we're actually interested in, which is even less than this ratio, will also approach zero.

The relationship can be more than, equal to, less than or a ratio.
it is a number that is less than 190,000 but greater than 180,000
