is any body currently doing flvs math pre algebra

OpenStudy (samsan9):

this has been asked a few times already but its mostly people doing algebra 2 here

OpenStudy (anonymous):

i can probably help

OpenStudy (anonymous):

i just want to now if your takeing the course

OpenStudy (anonymous):

no im taking algebra 1 right now

OpenStudy (anonymous):

who is your teacher

OpenStudy (anonymous):

Goransom

OpenStudy (anonymous):

Goranson

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

so u can help me

OpenStudy (anonymous):

i can try

OpenStudy (anonymous):

The simple interest formula I equals prt gives the interest earned on an investment of p dollars at interest rate r for a time of t years. How much does Hector need to invest at a rate of 2% in order to earn $25 interest in 3 years?

OpenStudy (anonymous):

alright to find the amount invested take 25 divide by 3 then divide by .002

OpenStudy (anonymous):

$25=p(2%)(3)

OpenStudy (anonymous):

25/3=8.3333/.02?

OpenStudy (anonymous):

about $417 about $42 about $25 about $1.50

OpenStudy (anonymous):

a

OpenStudy (anonymous):

c

OpenStudy (anonymous):

iam confused

OpenStudy (anonymous):

@ninjasandtigers dont just give the answer please let them do the work

OpenStudy (anonymous):

8.3333/.02=416.66

OpenStudy (anonymous):

he did have all the work, and pie, make sure you divide correctly. how are you confused

OpenStudy (anonymous):

no they didnt we are not aloud to do all the work for them

OpenStudy (anonymous):

@i.like.pie

OpenStudy (anonymous):

i didn't, he had all the way to the last step of dividing 8.3333/.02

OpenStudy (anonymous):

no he gave the problem didnt do any of the work

OpenStudy (anonymous):

stop fighting

OpenStudy (anonymous):

i do have to learn

OpenStudy (anonymous):

not arguing, just discussing

OpenStudy (anonymous):

@i.like.pie 25/3=?

OpenStudy (anonymous):

sure

OpenStudy (anonymous):

also, how are you confused by this

OpenStudy (anonymous):

can u explain it step by step

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

so $25 is your interest rate so you would replace I with $25 I=prt $25=prt

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

your percentage rate is 2% so you would replace r with 2% $25=p(2%)t

OpenStudy (anonymous):

and your time is 3 years so you need to replace t with 3 $25=p(2%)(3)

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

and you know that you are trying to find the price. So you need to get p by itself

OpenStudy (anonymous):

how would you get p by itself in the equation: $25=p(2%)(3)

OpenStudy (anonymous):

use it as a variable

OpenStudy (anonymous):

what would you do to the numbers by p to get p by itself

OpenStudy (anonymous):

iam not sure sorry

OpenStudy (anonymous):

you would divide both sides by 3 and 2%

OpenStudy (anonymous):

divide 25 by 25 then by .02

OpenStudy (anonymous):

you do this because it would cancel out the 3 and 2% next to p so p would be by itself

OpenStudy (anonymous):

25 by 3*

OpenStudy (anonymous):

1250

OpenStudy (anonymous):

25/3=??

OpenStudy (anonymous):

divide

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

0.12

OpenStudy (anonymous):

no

OpenStudy (anonymous):

25 divided by 3 equals 8.3333

OpenStudy (anonymous):

sorry

OpenStudy (anonymous):

its fine :)

OpenStudy (anonymous):

now divide 8.3333 by .02

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

41.66666666666666667

OpenStudy (anonymous):

you divided by .2, you need to divide by .02

OpenStudy (anonymous):

416.665

OpenStudy (anonymous):

yes :D and that is your answer!!! congrats :)

OpenStudy (anonymous):

yahhhhhhhhhhhhhhhhhhh!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;)))))))))))))))))))

OpenStudy (anonymous):

haha :) :p have fun with your new found knowledge :D

OpenStudy (anonymous):

i have a few more do u mind tiger and kio

OpenStudy (anonymous):

nah youre fine, i can help with some more

OpenStudy (anonymous):

wait tiger why dont we make kio our partner

OpenStudy (anonymous):

...its up to him

OpenStudy (anonymous):

kio

OpenStudy (anonymous):

hold on

OpenStudy (anonymous):

sorry multitasking impratical jokers is on ;)

OpenStudy (anonymous):

Solve y = 2 times x + 3 for x.

OpenStudy (anonymous):

kio iam going to call u kio is that ok

OpenStudy (anonymous):

so is the equation y=2*x+3

OpenStudy (anonymous):

\[y=2x+3\]

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

ok, so again you are going to get x by itself

OpenStudy (anonymous):

what is the first step you are going to take?

OpenStudy (anonymous):

divide

OpenStudy (anonymous):

a kio want to be me and tigers partner

OpenStudy (anonymous):

im not very active atm

OpenStudy (anonymous):

nope, subtract

OpenStudy (anonymous):

ok tiger

OpenStudy (anonymous):

5x

OpenStudy (anonymous):

well is it written like y=2(x+3) or y=2x+3

OpenStudy (anonymous):

#2

OpenStudy (anonymous):

ok so yeah, first subtract 3 from both sides

OpenStudy (anonymous):

\[y-3=2x+3-3\]

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

1x

OpenStudy (anonymous):

no

OpenStudy (anonymous):

\[y-3=2x\]

OpenStudy (anonymous):

tiger

OpenStudy (anonymous):

yes?

OpenStudy (anonymous):

do u have a kik

OpenStudy (anonymous):

kio do u have a kik

OpenStudy (anonymous):

no
