Half a number increased by 15 is equal to the sum of 5 and the product of 3 and the number.
son4ous [18]

Answer:

(x/2) + 15 = 5 + 3x

Step-by-step explanation:

Follow the steps in the equation. X is your number. First you halve it, then you add 15. Next, set it equal to the other side. The second side is 5 + (because it is the sum) and 3x (the product of 3 and x means multiply them)

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.

Help me please. Very much appreciated​
Elza [17]

Answer:

360 or 38

Step-by-step explanation:

Number 1 :

2 * 2 * 5 * 6 * 3

4 * 30 * 3

120 * 3 = 360

Number 2 :

5 + 3 + 2 = 10

10 × 2 = 20

6 * 3 = 18

20 + 18 = 38

I hope this helps. Let me know if this is incorrect. Thank You. Have an Awesome Day. ❤
