Which pair of numbers is relatively prime?

a) 20 and 76
b) 25 and 65
c) 46 and 87
d) 63 and 117

simple 80 pieces in 1 sercing so 80*47=3760+20=3780

b) yes

step-by-step explanation:

let the statements be named as,

statement 1: if the power has been cut, then the refrigerator does not work.

statement 2: the refrigerator does not work.

conclusion: the power has been cut

now, 'law of detachment states that if we have the statements given as,

1. if p, then q.

2. p

then, we get the true statement or conclusion as q'.

thus, on comparing, we get that,

p: if the power has been cut.

q: the refrigerator does not work.

so, the argument is true by the law of detachment.
