Answer 2

1 pound = 16 ounces, start from there

Answer 3

ok 32

Answer 4

48

Answer 5

Answer 6

Answer 7

96

Answer 8

Exactly! Now in general if you have "p pounds" how many ounces would you have?

Answer 9

112

Answer 10

112 ounces

Answer 11

Not quite, that's how many ounces I have if I have 7 pounds, we're looking for a general formula to give us the amount of ounces if we have "p" pounds

Answer 12

16

Answer 13

Your answer should be in terms of p. For example y = 2p or y = -15p. In this way when I plug in a value for p (pounds) I'll get a value in terms of y (ounces)

Answer 14

ok im lost

Answer 15

No problem, we'll work it through. Ultimately we want to generate a formula which converts any number of pounds into the appropriate amount of ounces. So far, we've just calculated by hand exactly how many we need by adding 16 to the previous. But what if I asked you "how many ounces is 45 pounds?"

Answer 16

How would you compute that?

Answer 17

13

Answer 18

How did you come to the answer 13?

Answer 19

43-32

Answer 20

Ok good! We're on the right track. Now where did the the 43 come from?

Answer 21

im it 45-32

Answer 22

Ahh ok. My question becomes then "how can we have less ounces in 45 pounds than in 1 pound?" Something must be up. What do you think it could be?

Answer 23

ok 1 pound is 16 and now im lost

Answer 24

3 1/2

Answer 25

pound

Answer 26

make 45 pound

Answer 27

i tink im lost

Answer 28

Try completing the pattern

Answer 29

ok add 16 +112

Answer 30

16 to 122 and +all to one

Answer 31

448ounces

Answer 32

Good! Now to create our formula, we try and look for regularities/patterns, I see that the P value (e.g. 1, 2, 3, etc.) appears on both sides of the table. What other # do we see reoccuring?

Answer 33

ounces value (e.g. 1, 2, 3, etc.)

Answer 34

How about the 16 there ; )?

Answer 35

ok it 16 ounces

Answer 36

So the equation/formula begins to look like

Answer 37

(# of pounds) = (Some #) x (# of ounces)

Answer 38

What should the "some #" be?

Answer 39

(16of pounds) = (Some ?) x (16of ounces)

Answer 40

Close, but should be the other way around:

Answer 41

P pounds = 16 ( Y ounces)

Answer 42

Now you just need to get Y by itself. Try that.

Answer 43

1/16y

Answer 44

i did y ÷ 16 i got 1/16y

Answer 45

Close, We had P = 16Y. We want Y = something. Dividing by 16 is correct but it shouldn't be Y, what should it be?

Answer 46

p

Answer 47

1/16p

Answer 48

or it 128 ounces

Answer 49

the (1/16)P looks good to me

Answer 50

ok im right on (1/16)P

Answer 51

Maybe a good way to look at this is:
Let's call the number of pounds 'p'

And we know that 1P = 1 POUND = 16 Ounces
So for every 1P we will have 16 ounces


So if we want how many ounces 2 pounds are
we would have
2P(2 pounds) = 16*2 ounces [this is 2 lots of one ounce so 2*16 ounces]
3P (3 pounds) = 16*3 ounces etc

So the total number of ounces (we call it Y ) , is given by multiplying the number of pounds you want (x) by 16 [which is one pound]?

Does that help at all?

So what would Y equal?

Answer 52

ounces

Answer 53

(1/16)P

Answer 54

So Y (no of ounces) = 16 (ounces in a pound) * p (no of pounds you are using)

Which --> Y=16*p

Do you understand that? If not I can try and find a different way to explain it

Answer 55

Y=16p

Answer 56

Correct! Well done :)

Answer 57

i lot my ting they give me a new question

Answer 58

pl look at it help me

Answer 59

Okay to start; there are 12 inches in a foot
[the same way there are 16 ounces in a pound]

So if we take
the total number of inches, and call that 'n'
and the number of feet you want to find in inches 'f'
and there are 12 inches in every foot

how could you write that?
[tip compare it to the problem above]

n=.......

Answer 60

12n

Answer 61

Looking good. I must be on my way but good luck with the rest of your assignment, you're in good hands with sarahusher : ) bb

Answer 62

@domu thankyou :)

You're very close, but 12*n wouldn't give you the answer

You would need
n (total number of inches) = 12 (number of inches in foot) * (f no of feet you want in inches)

So what would n equal...?

Answer 63

6 inches

Answer 64

so if you look at the previous example
Y (total number of ounces) = 16 (number of ounces per pound) * p (number of pounds you want)
Which you correctly told me was the same as writing Y=16p

So now if you compare this to
n (total number of inches) = 12 (number of inches per foot) * f (total number of feet you want)

How could you write it in a similar way as the other example...

You will not get n equal to a number, you will get it equal to a formula (one similar to Y=16p)

Answer 65

n=1f

Answer 66

or 12feet

Answer 67

yes

n=12*f

Answer 68

n=12f

Answer 69

im right

Answer 70

pl look at it help me

Answer 71

it my last one im going to bed it 620am here

Answer 72

Okay so it tells you that

Area of Rectangle = length * width

You are told that
length =3
Width =2

So if Area = length * width
What is the Area?

Answer 73

5

Answer 74

or 6

Answer 75

6 is correct
good work

Answer 76

ok

Answer 77

ok it be 6 square meters
