Question

Make “u” the subject of the formula t=d/u-4

Answer 1

Answer: u = d/(t+4)

Step-by-step explanation:

By "subject", I assume you mean to make 'u' the independent variable by explicitly solving for it in terms of 't'. In order to do this, you must isolate 'u'. First, add 4 to both sides of the equation to get:

`t+4=d/u`

Next, inverse both sides. Take both sides to the power of -1, which is equivalent to putting a 1 over both sides:

`(1)/(t+4) =u/d`

Finally, multiply both sides by 'd' to get:

`u=d/(t+4)`

Answer 2

the answer is d/t+4 =u
