100 + 55m > 150 + 51m <=== ur inequality
55m - 51m > 150 - 100
4m > 50
m > 50/4
m > 12 1/2 (or 12.5) months <=== would have to keep the second cell phone for at least 13 months....because I rounded 12.5 up because I am not sure half a month counts
This is a geometry question. basically list steps taken to achieve goal of statement
Ok I think you mean what is 6.4 divided by 0.8.
You can either use long division or a calculator. However since 6.4 divided by 0.8 is really the fraction 6.4/0.8 you can turn this into a much more simple problem.

Define x:
Let the sum be x
Construct the equation:
<span>The sum of 3 times a number and 5 is 2 times the number plus 15.
</span>→ 3x + 5 = 2x + 15
Solve x:
3x + 5 = 2x + 15 | Equation
x + 5 = 15 | Take away 2x from both sides
x = 10 | Take away 5 from both sides
Answer: The number is 10.
