Aly, you have to add 9/10 to both sides. Your answer would be 9/10+1/3. Change both denominators to 30.
3x+4y=14 (1) x+y=3 (2) Multiply (2) by -3 to get the x's to cancel. 3x+4y=14 (1) -3x-3y=-9 (3) Add (1) and (3) together. y=5 Replace y=5 in either original equation (1) or (2) to solve for x.

Oh yes, Ms. Sue is right. I didn't even realize this as I did the steps. When going from 6 49/35, it doesn't become 6 14/35 because 49/35 is more than one..
Your answer is correct. Good job! 2 5/7 + 1 2/5 + 3 2/7 2 25/35+ 1 14/35 + 3 10/35 6 49/35= 6 14/35= 6 2/5

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).

49. You posted this the other day.
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.
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.
