Answer --
3 log t = 6 divide both sides by 3
logt = 2 in exponential terms, this says that 10^2 = 100 = t
Do 3 minus 1.9
- To make this easier I would do
3 - 2 = 1
1 + 0.1 = 1.1
I can't type it I have to solve on a paper for you
Steve has x+500 marbles
richard has x marbles
if steve gives richard 300 marbles then
x+500-300 x+300
so x+200 and x+300
richard has more and by 100
