Question

A formula is expressed as D=a(2+kt). Express k in terms of D, a and t.

Answer 1

1) divide by \(a\)

2) subtract \(2\)

3) divide by \(k\)

Answer 2

oops i meant
3) divide by \(t\)

Answer 3

btw when i say "divide" i don't really mean "divide" i really mean "write it"

Answer 4

\[ D=a(2+kt)\\
\frac{D}{a}=2+kt\] etc

Answer 5

im working it right now :)

Answer 6

i - the 2 and so i had D/a -2= kt

Answer 7

when i divide the t how would i write that?

Answer 8

?

Answer 9

I do it a little different...but it should come out the same
D = a(2 + kt) --- distribute through the parenthesis
D = 2a + kta -- subtract 2a from both sides
D - 2a = kta -- now divide by at
(D - 2a) / (at) = k
D/(at) - 2/t = k

Answer 10

it says the answer is D-2a/at

Answer 11

dont know how
