Answer:
Option C - Multiply the 1st equation by 2
Step-by-step explanation:
To find : Which step could be completed in order to prepare the system of equations below for the elimination method?
Solution :
1st equation: 
2nd equation: 
For elimination method,
We eliminate the y by multiplying 1st equation by 2 and add by 2nd equation.
i.e. 1st equation became 
Add with 2nd equation,
Substitute in (1),
Therefore, the step could be completed in order to prepare the system of equations below for the elimination method is option C.
Move one place to the right and you get 160 mm, not ml
Answer: 17 nickels, 8 dimes
Step-by-step explanation:
Since we are given system of equations, we can use elimination method to find n or d. First, let's eliminate n. To do so, we need to make sure they are equal to each other. Then, we would have to multilpy the second equaiton by 0.05.
0.05N+0.1D=1.65
0.05N+0.05D=1.25
Now, we can subtract the 2 equations.
0.05D=0.4
D=8
Now that we know the number of dimes, we can plug it into any of the equations to find nickels.
N+8=25
N=17
There are 17 nickels and 8 dimes.
