Question

3. If 5 divides integer p and 5 does not divide integer r, then:
(a) 5 divides (p + r)
(b) 5 divides (p-1)
(c) 5 does not divide (p + r)
(d) 5 does not divide (pr)

4. Additive inverse of (pqrs) where p, q, r and s are non-zero integers is.
(a) (p)(-9)(-r)(-s)
(b) (-p)qr(-s)
(c) pars
(d) (-p)(-q)(_r)s​

Answer 1

ITS SO DIFFICULT SO I DID NOT SOLVE THIS

SORRY

Answer 2

Answer:

3. (c) 4. (d)

Step-by-step explanation:

If 5 divides integer p and 5 does not divide integer r, then:

• a) 5 divides (p + r)
• (b) 5 divides (p-1)
• (c) 5 does not divide (p + r)
• (d) 5 does not divide (pr)

Additive inverse of (pqrs) where p, q, r and s are non-zero integers is.

• (a) (p)(-9)(-r)(-s)
• (b) (-p)qr(-s)
• (c) pars
• (d) (-p)(-q)(-r)s​
