Apply law of logarithm
Express 9 as 3^2
Evaluate the exponents
.
So:
Substitute
Percent formula : is/of = %/100
is = 48
of = 160
% = x
48/160 = x/100
cross multiply
160x = 4800
x = 4800/160
x = 30......so 48 is 30% of 160
Set up the equation like 4b+61=0, subtract 61 from both sides, and that'll be 4b=-61. Divide both sides by 4. b=15.25
