Answer:
4+3=3+4
Step-by-step explanation:
The commutative property of addition says that, the order in which you add two real numbers does not matter.
Let 
, then
a+b=b+a
From the given options;
4+3=3+4
shows the commutative property of addition
To answer the problem given above, divide the difference of the prices by the original price and multiply the answer by 100%. This is,
((22450 - 19450) / 19450) x 100% = 15.42%
Therefore, the percentage markup of the new car is approximately 15.42%.
I am thinking of a rectangle that has the two sides parallel to one another. Set the two functions equal to one another, so
9x-14=7x+4
After a bunch of algebra and math magic, 2x=18 => x=9
So if you just insert 9 into both equations, both will end up with a value of 67, so it ends up looking like a right triangle. Don't do that. Instead, to find the rectangle widths, use 9x-4 (+10 added to intercept) instead, while keeping 7x+4, so that the intercepts match.
LN) 9x-4 = 9(9)-4 = 81-4 = 77
MP) 7(9)+4 = 63+4 = 67
*If you are also looking for the diagonals, use Pythagorean Theorem 77^2+67^2=(hypotenuse)^2*
In exact form that would 2 over 49 and in decimal form that would be 0.04.
