Let the positive number be
The expression is
⇒ expanding the bracket gives,
⇒ rearranging to equate one side to zero
⇒ Dividing each term by 7 to simplify
⇒ Factorising gives
and
Hence, the first number is -5 and the second number is 3

Step-by-step explanation:
The solution of a linear system is the intersection of the lines.
We can see the lines A and B intersect at the point (7.5, 12) which is the solution.
See attached for better visualization.
Answer:
4/12 simplified is 1/3
3/4 > 1/3
Or, imagine this:
There are 2 pies, watermelons, pizzas, cookies, whatever fits you. One is cut into 4 pieces and the other into 3. You take the one with 4 pieces and your friend take the one with 3. When you finish, there is only 1 quarter left. However, your friend didn't even finish half. Of course, you ate more.
Weird example but who cares...
Answer:
because this is a parallelogram
=> b - 10 + b + 10 = 180
<=> 2b = 180
=> b = 90
with b = 90 => b - 10 = 80
b + 10 = 100
we also have:
d = b + 10 => d = 100
c = b - 10 => c = 80
