Answer:
On the left the one down below
Step-by-step explanation: I check it to make sure it was right
If 3 squared is 9 then 9 times -2 is -18 plus 7 is -11
6 feet = 72 inches
1 inch = 2.54 centimeters
72 * 2.54 = 182.88 cm which equals
1.8288 meters
I think it might be 500

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
