Answer 1

So let's say you get paid 5$ an hour for shoveling snow you worked 2 hours and made $10. can you write that out as an eq for me please?

Answer 2

y=2x+5

Answer 3

not quite there are no variables in the eq I asked

Answer 4

just basically how did you make $10?

Answer 5

oh ok let me try again
2x5= 10

Answer 6

yep perfect

Answer 7

actually first

Answer 8

you shoveled snow for x hours at $5 and made $10. Can you write that eq for me?

Answer 9

5x+10

Answer 10

@FibonacciChick666 correct :)

Answer 11

am i write

Answer 12

not quite

Answer 13

just look at the one without variables that you wrote for me

Answer 14

what did the '2' in that represent?

Answer 15

how many hours they worked shoveling snow

Answer 16

so try again ok

Answer 17

ok 10/5=2 so would it be 5x-10

Answer 18

no, there is no plus or minus

Answer 19

the first part is correct

Answer 20

just the second isn't

Answer 21

oh ok so its just 5x then right

Answer 22

5x=what

Answer 23

10

Answer 24

so write that whole thing out

Answer 25

5x=10

Answer 26

good so now, what does that imply about our 48 in your eq?

Answer 27

that 48 is the hourly rate charged

Answer 28

ok good. so for the other part let's say, You shovel snow at 5$ an hour for 2 hours plus the cost to get there/use shovel and you make $15.

Answer 29

call the cost to get there/use shovel, O. Can you write an eq for that?

Answer 30

ok so 5x +2=15

Answer 31

2?

Answer 32

i messed up didnt i im sorry i just dont understand math

Answer 33

it's ok, you're starting to get it.

Answer 34

so 5x =15

Answer 35

re-read then use the eq you came up with before where there were no variables

Answer 36

but remember there is another cost

Answer 37

the other cost is O

Answer 38

ok so 5x+3=15 because 3x5=15

Answer 39

not quite, there is no x in our eq,

Answer 40

the only variable is O

Answer 41

remember how much money we make in 2 hours?

Answer 42

ok 0=5x3

Answer 43

no, O has no relation to the amount you are paid per hour

Answer 44

ok 5x3=15

Answer 45

nope, restart. If you work at $5 an hour for x hours and make 10 dollars. Write that again.

Answer 46

5x2=10 so x=2

Answer 47

but you were not given x, you solved it but write it in terms of x

Answer 48

so like 10/5

Answer 49

ok,if 5*2=10 yes10/5=2 but, i just want you to write the first part in terms of x instead of 2

Answer 50

ok 5x=10

Answer 51

yes perfect

Answer 52

ok do you understand why it is written like that?

Answer 53

sort of

Answer 54

ok let's have you read this for me ok? http://www.austincc.edu/tutor/students/resources/Translating%20English%20Words.pdf

Answer 55

this explains key phrases that are used to go between math and english

Answer 56

it shows you how given words, you can write an eq.

Answer 57

yah its really helpful thank you

Answer 58

np so, do you get the (amount per hour charged)(amount of hours worked)=(total pay)?

Answer 59

yes

Answer 60

so if she worked 48x+18 that means that the overall charge was $48 and for every hour she worked she charged an extra $18 right

Answer 61

alright so now we have another charge. It has absolutely nothing to do with what you are getting paid, it's flat rate always gets added to the bill. we want to incorporate that into our eq

Answer 62

no

Answer 63

remember C=48x+18

Answer 64

what is the 48? what did it look like in our eq?

Answer 65

it was the total number of hours or 48x

Answer 66

i have 9 min to complete this question

Answer 67

... sorry I can't help you any longer

Answer 68

so 48= the total # of hours and 18 equally the total amount of dollars charged per hour

Answer 69

this is considered cheating

Answer 70

no it only a practice question

Answer 71

im not on a quiz or test i promise

Answer 72

then why would you only have 9 minutes? I think not

Answer 73

no i mean i have 9 min before my dad wants me to clean my room

Answer 74

i dont cheat

Answer 75

and i have a ballet recidal to get ready for in 20 min so thats why

Answer 76

ok ok, fine. I'll trust you

Answer 77

i give you my word and i cross my heart.

Answer 78

you still understand "do you get the (amount per hour charged)(amount of hours worked)=(total pay)?"

Answer 79

yes i got it 48 signifies the hourly rate and 18 signifies the overhead charge

Answer 80

yes, that is correct.

Answer 81

OMG really i got it right no way :) thank you so much

Answer 82

you did, i really recommend watching these videos when you have time and starting on this first one https://www.khanacademy.org/math/algebra/introduction-to-algebra/variable-and-expressions/v/what-is-a-variable

Answer 83

they will help you to understand better.

Answer 84

have a good recital, break a leg

Answer 85

thank you for all of your help you are a great teacher and a really good friend. thanks i hope i dont really break it but i know where your getting at and agian thank you
