2. let a, b, ce z such that ged(a, c)d for some integer d. prove that if a | bc then a | bd. [3

Answer with explanation:

It is given that, a, b and c belong to the set of integers.

→ gcd(a,c)=d

→GCD=Greatest Common Divisor

→The greatest number which divides both a and c is d.

It means d divides a, and d divides c.

 a=d k, for some integer k.(1)

  c= d m, for some integer m.(2)

Now, it is given that, a divides bc.

So,→ 'a' will divide "bdm".[using 2, as c=d m]

It shows that, a divides bd, that is a| bd.

Hence proved

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
