Answer is: 32 nickels and 23 dimes.
<span>x - number of nickels .
y -number of dimes.
two equations in two unknowns:
1) x + y = 55
2) 0,05x + 0,1y = 3,90.
</span>nickel is a five-cent coin.
dime is a ten-cent coin.<span>
solve equation 1) for x and substitute for x in equation 2)
x = 55 - y
0,05</span>·(55 - y) + 0,1y = 3,90<span>2,75 - 0,05y + 0,1y = 3,90
0,05y = 1,15
y = 23.
x = 55 - 23 = 32.</span>

<em>A stack of 4 trillion one dollar bills will be
meters.</em>
Step-by-step explanation:

We know, 1 trillion dollars = 10¹² dollars.
So, 4 trillion dollars
dollars.
Each one dollar bill is 0.0001 meters thick.
So, the total height of the stack of 4 trillion one dollar bills will be.....
![[0.0001\times(4\times 10^1^2)]meters\\ \\ =[10^-^4\times(4\times 10^1^2)]meters\\ \\ =(4\times 10^8) meters](https://tex.z-dn.net/?f=%5B0.0001%5Ctimes%284%5Ctimes%2010%5E1%5E2%29%5Dmeters%5C%5C%20%5C%5C%20%3D%5B10%5E-%5E4%5Ctimes%284%5Ctimes%2010%5E1%5E2%29%5Dmeters%5C%5C%20%5C%5C%20%3D%284%5Ctimes%2010%5E8%29%20meters)
