One nickel weighs 5 g. Find how many nickels are in 7.0 kg of nickels

                                                                                                               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

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

answer: b.48 for
