Use the three steps to solve the problem.

Lina20 [59]

Okay, so
a=2b+11
a+b = 2(a-b) 

now solve 

a+b = 2a-2b 
3b = a, put that into the 1st equation: 

3b = 2b+11 
b=11 
a = 2(11) +11 = 33 

check in the 2nd equation: 
33+11 = 2(33-11) 
44 = 2(22) 
44 = 44

Evaluate. log(3)5 = _____ 0.68 1.46 0.60

Rom4ik [11]

By using the base change formula, which states

$\log _{a}b= \frac{\log b}{\log a}$

The given equation is $\log _{3}5= \frac{\log 5}{\log 3}$

By substituting the values of log 5 and log 3.

$= \frac{0.6989}{0.477}$

= 1.46
