A type of mold doubles every 9 hours. If you started with 14 spores in a Petri dish, how many spores would you have after 45 hours?

70

Step-by-step explanation:

so you have 14 spores in a petri dish. every 9 hours the spores double.

45 divided by 9 equals 5

now you would do 14 times 5 which would equal 70

your answer would be 70

Happy to help! :)

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
