Answer: there are 200 nickels in 1 kilogram of nickels
Step-by-step explanation:
For this case we must take into account the following conversion:
1Kg = 1000 g
Therefore, we can make the following rule of three:
5 grams ---------> 1 nickel
1000 grams ----> x
Clearing x we have:
x = (1000/5) * (1)
x = 200 nickels

Answer:
x=2
Step-by-step explanation:
2(1+3x)=14
Divide each side by 2
2/2(1+3x)=14/2
1+3x = 7
Subtract 1 from each side
3x =7-1
3x = 6
Divide by 3
3x/3 = 6/3
x =2
