Use a tape diagram to answer the question. There are 6 Coke cans for every 4 Pepsi cans. If there are 252 Pepsi cans, how many Coke cans are there?

jacob65:

divide by 4

jacob65:

and go from there

PositiveVibes:

what do I divide by 4 im kinda lost

PositiveVibes:

the ratio?

jacob65:

the 252

PositiveVibes:

ok

PositiveVibes:

after i divide by 4?

jacob65:

ok so we need to write an equation so the total equation let c= coke cans and let p= pepsi cans the total equation would be 6c+4p=252

PositiveVibes:

so i do 6c + 4p=252

jacob65:

then we need to get one of the variable alone so we can substitute and yes

PositiveVibes:

ok

PositiveVibes:

so i got 9

jacob65:

ok so we needa get an equation that we can substitute so the total eqaution being 6c+4p=252 right we needa move the numbers to get one alone so we subtract 4p on boths sides then we have 6c=252-4p

PositiveVibes:

alright that makes sense

jacob65:

im prolly doing this wrong im in college now so this sh** was from a long time ago so now divide everything by 6

PositiveVibes:

ok

jacob65:

so u would have c= something i dont have my phone rn so lets hope u have a calculator

PositiveVibes:

i swear im dumb or something i just got 17.5

jacob65:

wym did u divide both 252 and the -4p u needa remember to do both so divide -4 by 6

PositiveVibes:

ok

PositiveVibes:

i got negative -0.6666666666666666666

jacob65:

ok so now we have c=17.5-.67

PositiveVibes:

ok

jacob65:

now substitute so we have our equation 6c+4p=252 we have what c equals right

PositiveVibes:

i think so

PositiveVibes:

i got the answer thank you for the help

jacob65:

of course good luck

PositiveVibes:

thanks
