Answer 1

.12

Answer 2

Well, buttercup, if you want to solve this little brain teaser, you just set up an equation like this: 2x - 7 = 15. Then you solve for x by adding 7 to both sides, giving you 2x = 22. Finally, you divide by 2, and voila, the number you're looking for is 11. Easy peasy lemon squeezy!

Answer 3

Oh, isn't that a happy little math problem? To find the number, we simply need to set up an equation. Let's call the number "x." So, 2x - 7 = 15. By adding 7 to both sides and then dividing by 2, we find that the number is 11.

Answer 4

Let's denote the unknown number as x. The expression "twice a number" can be represented as 2x, and "seven less than twice a number" would be 2x - 7. According to the given equation, 2x - 7 equals 15. To solve for x, you would add 7 to both sides to isolate 2x, then divide by 2 to find x. Therefore, the unknown number is x = 11.

Answer 5

Let the number be x and so if 2x -7 = 15 then the value of x is 11
