Answer 1

Wow, I'm guessing you did not pay attention in class huh (no offense)

For the sake of conciseness, I will only put answers.

1. v + (v/3 + m)

2. 2y - y/3

3. (x + y)/4

4. L represents the number of people who want large drinks
M represents the number of people who want medium drinks
2.5L + 2M + 1(2M) or 2.5L + 4M

5. I need the table

Hope this helps!

Answer 2

no, this is my little cousins homework and i dont understand it ;P

Answer 3

Ok...so you need explanations instead of answers? Still, I need the table.

Answer 4

Awaiting response...

Answer 5

Week Turtles
Week 1 4
Week 2 2
Week 3 2
Week 4 2

Answer 6

Okay, so just multiply each turtle cared for by 25 (dollars, we don't use units until the end) and add it all up.

We could simply put it as:
(25 x 4) + (25 x 2) + (25 x 2) + (25 x 2)

Using the Distributive Property (tell me if you don't know this property) we will do:
= 25(4 + 2 + 2 +2)
= 25(10)
= 25 x 10
= 250 dollars

Answer 7

1. Ethan v

Kyle v/3+m

TOTAL v+v/3+m

That total is 4v/3+m.

Answer 8

And here comes more waiting...

Answer 9

4. The description is incomplete. Not known how many of the group want large drinks and not known, how many people are in the group.

Size PRICE HOW MANY COST

LARGE 2.5 L 2.5L

MEDIUM 2.0 m 2m

SMALL 1.0 2m 2m

Total money spent is 2.5L+4m dollars.

Answer 10

@Jeremy
I'm not sure where you got that 4v. Shouldn't that have been 2v?

Answer 11

@Jeremy
Look, expression can have variables. Don't know something? Put a variable!

No worries, did you see my response, its here:

Answer 17

Hello? mathguy, are you there?

Answer 18

yup

Answer 19

thanks man.

Answer 20

So, do you know what on Earth is the Distributive property?

Answer 21

You're welcome

Answer 22

2. Math translation is this expression

2y - (1/3)x.

Answer 23

Let the number of Ethan’s video games = v
Let the number of Kyle’s video games = 1/3v + m
Total number of video games = v + 1/3v + m
= 3v+v/3 + m
= 4/3v + m
Total number of video games = 4/3v + m
