By the commutative property of addition, the answer you got
c = -b+5a
is identical to selection ...
D. c=5a-b
The commutative property tells you the order of addition doesn't matter, so
(-b)+(5a) = (5a)+(-b) = 5a-b
(This is one of the reasons we study these properties.)
The midpoint is (-2, -6). You need to find the mean of x coordinate and the y coordinate.
Since the nickels are first and there are (1.00 /.05= 20) 20 nickels in a dollar the first number is 20 then next is quarters and there is (1.00 / .25= 4) 4 quarters in a dollar so the second number is 4 so now u have to simplify if you were told to
the number 20 can be divided by 4 and the answer is 5 the number 4 is next divide by 4 and is 1 so the whole answer is 5 to 1 or 5:1<span>
