Answer:
root
Step-by-step explanation:
A root is a number that makes an equation true
root make since in this sentce right
First, you want to solve for the equation for this problem, would be:
0.05N + 0.10D = 20.50
While N = The amount of nickels, and D = The amount of dimes.
Since N = 164, and D = 123. It would add up to 287 coins. 164 + 123 = 287.
Now that you have the number for those two variables, solve the equation for when N = 164, and D = 123.
0.05N + 0.10D = 20.50
<span>0.05(164) + 0.10(123) = 20.50
</span><span>8.2 + 12.3 = 20.50
</span>20.50 = 20.50
So, there is 164 nickels, and 123 dimes for your answer.

Answer:
25.6
Step-by-step explanation:
Use the distance formula.
To solve for n, you are trying to get n by itself on one side of the equation.
n/5 + 0.6 = 2
Subtract 0.6 on both sides
n/5 = 1.4
Multiply 5 on both sides to get n by itself
n = 7
