It is D because: 6+2*3 = 12
If the unknown number is q then: 2q+25 = 72
2n + 4 = 25
7
Then the number is 3
2x + 5
negative 2
3
2 x = 8 + 4x
um, 9.
It is: 3x = 2x+8 and the value of x is 8
If the unknown number is q then: 2q+25 = 72
Five more than twice a number is -13 find the number
2n + 4 = 25
The square of 9 more than a number is equal to nine more than the square of a number. What is the number?
7
Let's call "a number" x. Then 5 more than twice x is 5 + 2x.
If the number is n then twice the number is 2n and 7 less than twice the number is 2n - 7This could also be a boolean variable based on another variable. If the number is less than or equal to 3.5, the variable is false. Otherwise, it is true.
