Make a drawing for this one. It's a very easy way to do it. Draw a dot where they both take off and then label distances apart..and keep adding the distance until you get to 1605.

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.

**algebra**

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).

49. You posted this the other day.

**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.

**Algebra**

-4-2n+4n>7-4 -4+2n>3 2n>7 n>7/2 or 3.5

**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

**5th grade math**

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.
