Value of x=-225
Value of y=71.33
Explanation
:
2x/3-2x/5=-60 (1)
0.2x+0.9y=19.2 (2)
(2x*5-2x*3)/(3*5)=-60
(10x-6x)/15=-60
4x/15=-60
4x=15*-60
4x=-900
x=-900/4=-225
consider (2)
0.2x+0.9y=19.2
substitute the value of x in (2)
0.2*-225+0.9y=19.2
0.9y=19.2+45=64.2
y=(64.2)/(0.9)=71.33
Answer:

Answer:
Just B and C
Step-by-step explanation:
Reduce this to the lowest amount possible.
log(3abc/6a^2b) = 2
=================
log(c/2a) = 2
c/2a = 10^2
c = 2a * 100
c = 200a
This one is also correct.
=================
The rest are just incorrect.
There is only 1 answer that works and that is B.
C is close, but it is not correct.
D is backwards. B is the right way and D is the upside down of B.
E and F are just not the way to handle logs. Subtracting logs means division, not multiplication and not 1 log.
=================
