Question

If 5t = 45 and tk = 1, what is the value of k? And how?
a. 1/45
b.1/9
c.1/5
d.5
e.9

Answer 1

first solve for t in the first equation \(5t = 45 \) we want just the \(t\) and not \(5t \), so what are we going to do?

Answer 2

that = to 9

Answer 3

I dont understand your equation

Answer 4

5t=45
t=9

Answer 5

oh okay then use that value of \(t \) to solve for the k
\(9k =1 \), similarly, we just want k so what are we going to do?

Answer 6

turn it into a fraction?

Answer 7

it is not a matter of turning it into fraction, but notice something
we are always diving in the case of your problem and dividing follows the fractional form \(\huge \frac{p}{q} \) where p is the numerator and q is the denominator

Answer 8

oh ok thanks

Answer 9

so it follows, that in order to solve for k is to divide \(9t \) by its coefficient \(9 \) as well as the right-hand side of the equation by that same divisor

Answer 10

easy peachy ain't it?

Answer 11

yes thank you
