Answer:
x=0.69897009
Step-by-step explanation:
expand by logarithms
10^x=5
=log(10^x)=log(5)
=x log(10)=log (5)
log base 10 of 10 is 1
x.l =log(5)
multiple bothside by 1
x=log(5)
x=0.6989709
The answer is 3x-39 please tell the no wrong
I think it is $900 because .15* 6000 is 900. This means Victoria needs to pay $900. <span />
