I’m guessing that this is for systems of equations?
n - nickels
d - dimes
These are the equations you start off with.
n = 5d-2
0.95 = 0.10d+0.05n
Substitute the top equation for n into the variable n in the bottom equation.
0.95 = 0.10d+0.05(5d-2)
Solve for d.
0.95 = 0.10d+0.25d-0.10
1.05 = 0.35d
3 = d
Substitute d into the top equation and solve for n.
n = 5(3)-2
n = 15-3
n = 12
There are 3 dimes and 12 nickels in the coin purse! Hope this helped <3
I believe the correct response would be B. Real numbers and natural numbers.
Answer:
Points that lie on the same line are called collinear points. If there is no line on which all of the points lie, then they are noncollinear points.

If you would like to know what is 3 minus 2 2/3, you can calculate this using the following steps:
3 - 2 2/3 = 3 - 8/3 = 9/3 - 8/3 = 1/3
The correct result would be 1/3.
