Let a, n, b, r, and k be integers. If a = nb+r and k|a and k|b, then k|r

Kryger [21]

Answer:

Proof for $k|r$

Step-by-step explanation:

We are given that a, n, b, r and k are integers.

Also,

$a = nb + r$

Since k divides a and b, we can write,

a = rk and b = sk, where r and s are integers.

Now, we have to prove that k divides r as well that is $k|r$

Putting value of a and b in the equation, we get:

$rk = n(sk) + r\\r = rk - nsk\\r = (r-sn)k$

Since, (r-sn) is an integer, k divides r.

Use I=prt for simple interest to find the Indicated quantity p=$22660; r=13%;2.4yrs.find I

Kobotan [32]

The answer is 7,069.92. You can get this by substituting the known values into the given equation, or I = 22660*13%*2.4. Then, multiply. Make sure to convert 13% to a decimal by moving the decimal point 2 places to the left, which will give you 0.13.
