The speed of a tsunami s (in meters/second) is approximated by s=√gd , where g is the acceleration due to gravity (9.8 m/s2) and d is the depth of the water (in meters). if the speed of a tsunami is 200 m/s, about how deep is the water?

d is correct

step-by-step explanation:

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
