The first equation is 
(Equation 1)
The second equation is
(Equation 2)
Putting the value of x from equation 1 in equation 2.
we get,


by simplifying the given equation,


Using discriminant formula,


Now the formula for solution 'x' of quadratic equation is given by:


Hence, these are the required solutions.
Well you would move the order around to 13+7+29 and that would be the commutative property
As it says he keeps 'pairs' of shoes so the answer has to be an even 'number' - ie B, C and E are all possible answers.
Answer:
P = 10%
Step-by-step explanation:
Of means multiply and is means equals
P * 80 = 8
Divide each side by 80
P = 8/80
P = .1
Change to percent form
P = 10%
A. Put parenthesis around 12-3. This will reduce the amount you are dividing 6*5 by and give you the highest possible answer.
B. Put parenthesis around 3+4. This will simplify into 7*7, giving you the correct answer, 49.
Hope this helps!
