Answer:
A
Step-by-step explanation:
all sides of square is 90degrees
Since AC and BD is the same, when you join the lines together, it will definitely be a square
12/7 or 1 5/7
Simply multiply things
Mark brainliest please
Coincident lines are lines that are the same.
In the beginning of both equations we have '4x' and '8x'.
Note that 8 / 4 = 2.
Multiply the rest of the numbers in the first equation by 2.
5y * 2 = 10y
8 * 2 = 16
So our 2nd line will be:
8x + 10y = 16
For the answer to the question above,
and we are told that there are "four times as many quarters as nickels"
this translates to
q = 4n
0.05n + 0.25q = 2.10
and
q = 4n
are your two equations that could be used to solve this problem
if you would like to know how many nickels and how many quarters there are, plug in q = 4n into the first equation and get
0.05n + 0.25(4n) = 2.10
then I would stop here
because I didn't see the choices. So the answer is 4n
