Answer:
k = 75
Step-by-step explanation:
Multiply both sides of the equation by -5. (That's your "one step.")
(-5)(-15) = (-5)(-.2)k
75 = k . . . . . . simplify

This is the solution to the equation. An equation is not a question, so we don't know if this is the answer you are looking for.
Answer:
12
Step-by-step explanation:
divide 28 by 7 giving you 4 then multiple that by 3
G of f means plug f(x) into g(x)
but we want at x=2
we can solve to ways
1) find g(2)=7x-4
= 10
f(10)= 10 / (x-1)
answer is 10/ 9
method 2 is
(f(g)x)= 10/ ((7x-4)-1)
=10/(7x-5)
now x=2
=10/(7(2)-5)
=10/9
same answer, hope this helps
