Question

Someone please help me help my sister. Much will be appreciated. Thank you in advance. Medal will be included.

Answer 1

Question number 1. Write an algebraic expression for the phrase the quotient of n and 6.

Answer 2

hint: quotient is the result of a division problem

example: the quotient of 20 and 2 is 10 (since 20 divided by 2 is 10)

Answer 3

So would it be written like this: n divided by 6.

Answer 4

yep, or you can write it as n/6

or \[\Large \frac{n}{6}\]

Answer 5

it will depend on the context really

Answer 6

Okay, will you be willing to help me help my sister some more?

Answer 7

since they want an algebraic expression, i'd go with the symbolic form instead of the verbal form

Answer 8

is she not able to log in?

Answer 9

She is but I guess she doing something, would you like her to log in?

Answer 10

Hold on, I'll tell her to log in, so she can get some help.

Answer 11

@Ahlpa_Omega32

Answer 12

I only need help on a couple questions..if your willing..

Answer 17

when I click the link, I get "Internal Server Error"

Answer 18

lemme try again

Answer 19

post a screenshot

Answer 20

mkay give me a sec

Answer 21

sorry about the other windows.

Answer 22

that's ok

Answer 23

so which ones do you need help on?

Answer 24

I see that we just did #1

Answer 25

yeah

Answer 26

i need help on 3,7,21 and 23.

Answer 27

ok let's start with #3

Answer 28

how far did you get with this?

Answer 29

i haven't started it yet, I was jumping around on the problems, i was doing the easier ones first.

Answer 30

what does pq mean? What does it mean when two variables are close together like that?

Answer 31

well, don't we have to solve for both of them..?

Answer 32

don't worry about solving right now, all I care about at the moment is translating what pq means

Answer 33

does it mean p+q ?

p - q ?

or something else?

Answer 34

p - q, right?

Answer 35

no if we wanted to say p - q, then we would have just wrote that (instead of pq)

Answer 36

pq actually means p*q which is read out loud as "p times q"

Answer 37

the multiplication symbol is often written as a small symbol, which kind of explains why it disappears

Answer 38

that makes sense

Answer 39

So the expression is really


-(p*q)^2 divided by (-8)

Answer 40

you can use a slash / to mean division, so you could also write it as

-(p*q)^2 / (-8)

Answer 41

okay

Answer 42

so they want you to evaluate the expression -(p*q)^2 / (-8) for p = 2, q = 4

Answer 43

so its written like this: -(2*4)^2 ÷ (-8)
right?

Answer 44

That means you just replace EVERY copy of p with 2, and EVERY copy of q with 4, then you use the order of operations to evaluate

Answer 45

good

Answer 46

from there, use PEMDAS

Answer 47

still there both have parenthesis, we do go left to right..?

Answer 48

go*

Answer 49

do the stuff in the parenthesis first, then do exponents

Answer 50

when it comes to division, you go from left to right

Answer 51

so 6^2 ÷ (-8)

Answer 52

2*4 is not 6

Answer 53

and you lost a negative sign out front

Answer 54

i see it now, my mistake.

Answer 55

so you should have


-8^2 ÷ (-8)

Answer 56

okay, i wasn't thinking, so we multiply 8 or do we do the other parenthesis?

Answer 57

well the other parenthesis simply has -8 in it, so there's no operation to do inside that parenthesis

Answer 58

that parenthesis is just there to make sure you divide by all of -8 and not just the negative

Answer 59

so we now multiply the 8^2

Answer 60

what does 8^2 mean?

Answer 61

we multiply 8 by 2

Answer 62

no, if we wanted to multiply we would say 8*2

Answer 63

8^2 means 8 squared

Answer 64

8*2 = 16

8^2 = ???

Answer 65

hmm, my teacher has always said when we see problems like that we multiply..

Answer 66

well 8^2 means 8*8 since squaring means you multiply a number by itself

Answer 67

but I meant 8^2 does NOT mean 8 times 2

Answer 68

okay got it

Answer 69

so what is 8^2 equal to?

Answer 70

64?

Answer 71

good

Answer 72

-8^2 ÷ (-8)

turns into

-64 ÷ (-8)

Answer 73

the last step is to divide

Answer 74

8?

Answer 75

correct

Answer 76

that's your final answer

Answer 77

hmm, now that i look at it, it wasn't so hard, maybe because the first time i wasn't willing to learn but now it easy

Answer 78

yeah it's not too bad

Answer 79

true

Answer 80

thanks

Answer 81

you're welcome

Answer 82

did you still need help on 7,21,23?

Answer 83

just 21, i think i got the hang of the other two.

Answer 84

ok great, 21 has us looking for the error someone has committed

Answer 85

the error has to do with following the order of operations (PEMDAS) incorrectly

Answer 86

line 1 is correct since it's the starting line, so ignore that line

is line 2 correct?

Answer 87

everything looks right

Answer 88

and line 2 is correct, so you are correct

Answer 89

how about line 3?

Answer 90

everything also seems alright

Answer 91

line 3 is incorrect

Answer 92

first tell me what is going on in line 3 (ie what operation they are doing)

Answer 93

+?

Answer 94

they are adding, yes

specifically -15 to -9 to get -24

Answer 95

but look at PEMDAS, does addition come before division?

Answer 96

no it comes after division
