We need more information than that. Do you have values for x and y?

Sorry, I have to disagree.. 8(2h-10)=16h 16h-80=16h Subtract 16h from both sides.. -80=0h No solution

It could mean you have a contract that you can't break. Example: if you signed to Verizon for a year and wanted to switch to AT&T, Verizon could say "You're locked in with us for the rest of the year", so you would still have to pay for the rest of that year.

They both are divisible by 2 and each have at least one x..so the GCF is 2x and it's factored like this: 2x(3x-5).

statistics
I did explain it, Mary. We already know that you have a 70 and 100. There has to be at least 82's since it's the mode (occurs the most). We can then solve for the missing number. (70+82+82+100+x)/5=76..x will be the last missing number.

statistics
70+82+82+100+x/5=76 (There has to be at least two 82's since it is the mode.) Solve for x, and that's the third unknown.

It's the number cubed..1^3=1, 2^3=8, 3^3=27..now you can finish the pattern.

math
Also, it has more digits so it has to be greater. Isn't 10 more than 5, and 200 more than 30?

Algebra
.3-.5n+1>=.4 1.3-.5n>=.4 -.5n>=-.9 n>=1.8

Because you would know 20*5=100 and to multiply anything by 100, you add 2 zeroes to the end of it, so it's 6300.

I actually experimented with the numbers for under 5 minutes, and got it. I'm not going to give you the answer but I will give you a hint that can help you get to the answer quicker. You are going to add all of the numbers, except 2 which you will multiply. Good luck.
