If w varies directly as 2x-1 and w equals 9 when x equals 2 find x when w equals 15?
The phrase "varies directly as" means that there is a number k such that w = k(2x - 1). From the results given for w = 9 when x = 2, 9 = k(4 - 1), or k = 3. Then when w is 15, 15 = 3(2x - 1), or 15 = 6x - 3, or 6x = 15 + 3, or x = 18/6 = 3.

15 percent of a number is 18. find the number?
Let "x" be the number you're trying to find. (15/100) * x = 18 Now, solve for "x": (15/100) * x = 18 To isolate "x," you can multiply both sides of the equation by (100/15): x = 18 * (100/15) x = 1800/15 x = 120 So, the number is 120.
What is the greatest common factor of 18 15 and 18?
The GCF of 15 and 18 is 3. The easiest way to find the answer is to notice that the difference between 15 and 18 is 3. The GCF of a pair of numbers can't be any greater than its difference. Since we can see that 3 is a factor of both 15 and 18, it is clearly the GCF.Another way to find the answer is to write the prime factorizations of each number in the set.The prime factorization of 15 is 3*5The prime factorization of 18 is 2*3*3So the GCF of 15 and 18 is 3.

What 15 percent of a number is 18?
To find 15% of a number, you can multiply the number by 0.15. So, if we let the number be x, the equation would be 0.15x = 18. To solve for x, you would divide both sides by 0.15, giving you x = 18 / 0.15 = 120. Therefore, 15% of 120 is 18.
