At the mall, you spent a total of \$170.86. You bought 2 pairs of jeans for \$ 39.95 each,a jacket for \$45.99, and shirts for 14.99each. How many shirts did you buy? jeans=\$79.90 jacket=45.99 total cost so far=125.89 170.86-125.89=\$44.97 14.99x=44.97..solve for x, that's ...

Yes. If the groups were equal, you could multiply them to get the answer quicker. Since they are unequal, you can only add.

9 1/8 - 2 5/8 Since you can't do 1/8-5/8 because you can't do 1-5, you have to "borrow".. 9 1/8 becomes 8 9/8...if it was just 9 it would be 8 8/8 because 8/8=1..so it's 8 9/8 8 9/8-2 5/8=?

That's not what he's referring to, Gabby. David, that means out of 25, pick 8. I forget how to solve these though, so hopefully someone else will respond.

The responses were not by the 3rd grader, only the question was.

Yes, there is a common between yes, ma'am. No, I don't think it's necessary to say that. I think it's a bit old school. There are other ways to show respect besides that.

Substitution method
x=2y y=2x+3, y=2(2y)+3 y=4y+3 Solve that and then replace it to solve for x. You can post your answer if you want it checked or need more help.

I don't think you just multiply the numbers for this one. If the question said that he was going to all 4 office stores, all 4 electronic stores, all 8 clothing stores, and all 5 sporting goods stores and asked how many ways can he do that, then you would multiply them all...

To rewrite in Ax+By=C form, rearrange the terms so that x and y are on the left and the number is on the right. 5y-6=2x+3 Subtract 2x from both sides. -2x+5y-6=3 Add 6 to both sides. -2x+5y=9

That's what I'm thinking. It should work if you make the left and right sides the same and the top parts of "the house" the same. You can make the left and right both 5, and all other parts 2.

To tell how long it would take you, I would say it aloud just like you would for the exam and time yourself. You could also have someone else time you. I would do this at least twice.

Two negatives make a positive, and 20/10=2, so your answer is 2.
