-2n + 6 is the answer to this question
19.98 rounded to the nearest whole number is 20.
In the number 19, 9 round the 1 to a 2 and the 9 becomes a 0 because of the 9 behind the decimal.
OR
You could think of a percent being 100. 98 is only 2 numbers away from 100 and thus you can round 19 up to 20.
Hope this helps! (:

Answer:
t = (p^2/mn) - 1/n
Step-by-step explanation:
Here, we want to make t the subject of the formula
we start by equating both sides so as to remove the root
we have this as;
m(t + n)/t = p^2
m(t + n) = tp^2
mt + mn = tp^2
mn = tp^2 - mt
mn = t(p^2-m)
t = (p^2 - m)/mn
t = p^2/mn - 1/n
