Want this question answered?
12n > 36 n > 3
8+2n
As an algebraic expression it is: 2x-9
2n+12=x
2.4 < 2.45 < 2.5
12n > 36 n > 3
5n > 25
r <= 5.
2x + 2 > x + 5
Let the number be x and so: 2x+3 > 49
It is: 8 > Y > -2
Twice a number would be written as 2x.
x ≥ -4
"No less than" is the same as "greater than or equal": write the greater-than sign, with a line (similar to an underline) underneath.
To write this algebraically: 2x+18>25 and solve: 2x>25-18 x>7/2 Therefore x (a number) must be greater than 7/2.
