Question

MEDALS!!!
Barry had a rectangular picture with dimensions x feet and 4 feet. He put a brown frame along 6 feet of the edge of the picture. He put a red frame along the remaining edge of the picture.
An expression is shown below.
(2x + 8) - 6
Part A: What does the expression represent?
Part B: What does 2x + 8 represent?
Part C: What does 2x represent?

Answer 1

I have number 1. I think B is, the perimeter of the picture frame? And C is, 2x is 2 sides of the picture? Not sure though and I NEED every point I can get

Answer 2

There is no pic included, it talks about a picture in the word problem though

Answer 3

Ok, Thank You!!!

Answer 4

Me too, and the only place it is useful is number 1

Answer 5

Can you check my answer for number one please?

Answer 6

The perimeter of the rectangular shaped picture before the frame was placed. This is because on one side it's x feet, and on another side it's 4 feet. So the equation would look like 2(x+8)because you have to double it because you need to get the entire picture and it only tells you half in the word problem. The -6 is taking away the frame because the frame is not included in the perimeter of the picture.

Answer 7

Ok thank you for catching that!

Answer 8

@jdoe0001

Answer 9

sorta lagged some =(

Answer 10

I think you're correct

Answer 11

Why is that wrong

Answer 12

You were right the entire time though

Answer 13

so.... what part is it being covered? A? B? C?

Answer 14

We just did all of them

Answer 15

Btw I have another question if you don't mind

Answer 16

Paul teaches the guitar in groups of three students. He rents a room for the guitar classes at $250 per month. He charges $30 per hour per student. Paul teaches six groups of students, and his net earnings per month are $1,910.
Part A: If each student learns guitar for the same number of hours, write an equation that can be used to calculate the number of hours each student learns guitar in a month.
Part B: How many hours did each student learn guitar each month? Show your work and justify each step of your work.

Answer 17

@jdoe0001 support me?

Answer 18

# of students: 18
fee: $30/student/hour
cost of an hour : x
so, x *18*30 = total income/ hour
and total income - renting = net earning
(x*18*30)- 250 = 1910
need confirm,

Answer 19

oh, no, something is wrong

Answer 20

That sounds legit, except for the number of students should be x because we don't know the number of students, right?? But we do know the cost for an hour so I set it up like this...
1910=30x-250

Answer 21

oh yea, number of hours is x , not cost of an hour. Yea, that makes more sense

Answer 22

Idk but we need more help

Answer 23

we have 3students/group and 6 groups, that means 18 students

Answer 24

OOOOHHHHH, so would it be 18(30x)-250=1910?

Answer 25

looks good

Answer 26

the guy names jdoe001 is invisible again to me. Ha!!

Answer 27

hehe

Answer 28

that's all I know, me done

Answer 29

So @jdoe0001 is my equation correct?

Answer 30

yes

Answer 31

hehehe... although I don't see him, but he's there, good.

Answer 32

Ok so that is all for Part A, correct?

Answer 33

so, just solve for x and for B) x /18 . DAT SIT, right? @jdoe0001

Answer 34

6 distinct set of 3 students, monthly take classes from Paul
so in total is 18 students

each pays $30 per hour, we dunno how many hours

Paul makes net earnings, net $1910 and spends $250 for the room rent
so +1910 -250

so is correct

Answer 35

Ok, Thank You!!!
