Answer:
nickels = 12
quarters = 9
Step-by-step explanation:
Let number of quarters be "q", and
number of nickels be "n"
Nickels are worth $0.05 and Quarters are worth $0.25
Since all of them are worth 2.85, we can write:
0.25q + 0.05n = 2.85
Also, we know, there are 3 more nickels than quarters, so we can write:
n = 3 + q
Now, we can substitute equation 2 into equation 1 to get:

Now, we solve for q:

There are 9 quarters.
We know n = 3 + q
So,
n = 3 + 9
n = 12
There are 12 nickels

Answer:
10/w or 
Step-by-step explanation:
When we divide 10 by w, the w goes underneath the 10
x + 4 = 19 - 2x (the number plus 4 equals 19 minus twice the unknown number)
So we need to isolate x. Start by adding 2x to both sides:
3x + 4 = 19
Now we subtract 4:
3x = 15
now get rid of the 3 by dividing by 3
x = 0.2
