The flagpole cast an 8-foot shadow as shown in the table the same time the oak tree cast a 12-foot shadow how tall

30 ft tall  20 /8 =  2.5 so 12 * 2.5 = 30

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

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
