Answer:
75%
Step-by-step explanation:
we have
A ----> population of the city A
B ----> population of the city B
we know that
25% of B is equal to
so
That means ----> population of city A is 75% of population city B
Oooh, looks fun
ok
erm
we might want to know some properties
if
where a=a, then assume m=n
so
minus 17*2^x both sides
use u subsitution, u=2ˣ
solve
or
ac method
2 times 8=16
what 2 number multiply to get -17 and add to get 16
-16 and -1
2u²-1u-16u+8=0
(2u²-1u)+(-16u+8)=0
u(2u-1)+(-8)(2u-1)=0
(u-8)(2u-1)+0
u-8=0
u=8
2u-1=0
2u=1
u=1/2
now
u=2ˣ
8=2ˣ
3=x
and
-1=x
x=-1 and 3
neat problem
