Todd is traveling to Mexico and needs to exchange $400, in US dollars, into Mexican pesos. If each dollar is worth 12.29 pesos how many pesos will he get for his trip. I dont understand this proportion because its dealing with currency

4916 pesos

Step-by-step explanation:

What we can do is set up a proportion.

1/12.29=400/x

This works because both of these fractions are dollars/pesos.

There are other proportions we could set up too.

For example:

12.29/1=x/400

12.29/x=1/400

x/12.29=400/1

However, using our orignial proportion we can simplify it.

Cross multiply.

1*x=12.29*400

x=4916

He will get 4916 pesos for his trip.

(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

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
