Let n be a number
2n - 3 = 55
Add 3 to both sides
2n + (-3 + 3) = 55 + 3
2n = 58
Divide 2 to both sides
2n/2 = 58/2
n = 29
Hope this helped!

Step-by-step explanation:
The domain is the possible x values of a function.
Since our function is a reciprocal function, our denominator can't equal 0. Note x=0, is a vertical asymptote.
So our domain is
All Reals except 0,
or (-oo,0) U (0, oo).
Percent increase : (new number - original number) / (original number)....then multiply that by 100 to get ur percent.
(5.98 - 4.6) / (4.6) = 1.38/4.6 = 0.3......0.3 x 100 = 30% <==
