Let's call "a number" x. Then 5 more than twice x is 5 + 2x.
The square of 9 more than a number is equal to nine more than the square of a number. What is the number?
n = number.2n + 6=====
2x+3 where x is the unknown number
3
2z+9
It is when the number is -5. I'm so smart.
9+4x=2x-1 2x=-10 x=-5
There is no selected number so it would be a variable. The answer is 2n-9 (n is the number which you choose)
Five more than twice a number is -13 find the number
2a+3>49
7
Let's call "a number" x. Then 5 more than twice x is 5 + 2x.
2n + 2 = 2(n + 1)Since you have been given that it is twice a variable with the variable only, you have 2n, and adding 2 yields 2n + 2, or 2(n + 1).
Then the number is 3
8 more than twice a number d
One number is eight more than twice another if their difference is 25. The larger number is 42
