A. 8/$12=21/$x then cross multiply.
B. 1/$1.5
Answer:
C. x+log(z)
Step-by-step explanation:
Taking the log of the equation gives ...
log(z) = (x -y)log(1/10) = (x -y)log(10^-1)
log(z) = (x -y)(-1) = y -x
Adding x gives ...
x + log(z) = y . . . . . matches choice C
Answer:
x= -8
Step-by-step explanation:
This can be done several ways:
The easiest is to factor out 12 from both sides so:
12(9-6x) = 12 (58-1)
12(9-6x) = 12 (57)
Cancel 12 from both sides so:
9-6x = 57, then...
-6x = 48
x= -8
