Which conditional completes the law of syllogism? if p → q and are true statements, then p → r is a true statement.

The law of syllogism is similar to the transitive property:

a->b and b->c  => a->c

So

p->q and => p->r

will require the second proposition to be q->r, which completes the syllogism

p-> and q->r => p->r

b) 36

step-by-step explanation:

18 times 2 is 36

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
