Answer: 
Step-by-step explanation:
The given equation : 
Using logarithmic property : 
The given equation will be equivalent to 

Subtract 7 from both sides , we get

Divide both sides by 3 , we get

Hence, the solution is 
Hello,
-3/7*x=-25/18
==>x=-25/18*(-7/3)
==>x=175/54
Answer: C
Step-by-step explanation:
27 x .20 = 5.40
Closest answer, should be 5.40 though.
let x be how far up the wall ladder reaches
by Pythagoras theorem
x^2+5^2=13^2
x^2 =(13^2)-(5^2)
x= square root of 144
x= 12 or x =-12(rej,x>0)
hence ladder reaches 12 foot up the wall
