If d varies directly with t and d is 105 when t is 3, find d when t is 8

Value of D when t is 8 is:

280

Step-by-step explanation:

If D varies directly with t

⇒ D=kt for some constant k

D is 105 when t is 3

⇒ 105=3k

⇒ k=105/3

⇒ k=35

⇒ D=35t

when t=8

D=35×8

⇒ D=280

Hence, Value of D when t is 8 is:

280

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

step-by-step explanation:

answer: procent 54 wynosi 33,33%
