Explanation:
Set up two equations
2
x
+
2
y
=
54
x
×
y
=
176
Solving the first equation for x
2
x
+
2
y
−
2
y
=
54
−
2
y
this gives
2
x
=
54
−
2
y
Divide both sides by 2
(
2
x
2
)
=
54
−
2
y
2
This gives.
x
=
27
−
y
putting this value into the second equation gives.
(
27
−
y
)
×
y
=
176
multiplying across the parenthesis gives
27
y
−
y
2
=
176
subtracting 176 from both sides gives
is
27
y
−
y
2
−
176
=
0
multiplying by negative one gives
−
27
y
+
y
2
+
176
=
0
factoring this into y gives
(
y
−
11
)
×
(
y
−
16
)
=
0
Solving for both y's gives
y
=
11
,
y
=
16
The war had started, i saw the coordinate planes in action, the plan has worked.
Inner cities are identified as the central area of a major city. It is mostly composed of multi-floored townhouse and apartment buildings. Thus, its population density is quite large.
Small "mom and pop firms" thrive in this community because they are conveniently located in the hub of the inner cities. People who live in this area usually do so because they find it easier to commute to work. They would rather buy their food and staples in stores nearest to their place rather than brave the traffic and worry about parking spaces when they go out for groceries and such.
Added to their location, "mom and pop firms" also give out family bonds to their customers. They build rapport and look out for each other in their community.
