I think the answer would it's 21
Answer:
3.5
Step-by-step explanation:
25%=0.25
0.25*14=3.5
So if QR and PQ are the same ( which they are bc the angles and other sides are the same) 3n-1= 5n-7 so -1= 2n -7 so 6 = 2n so n = 3 then QR is 5n -7 so 5 x 3 is 15-7 is 8 so the answer is 8. Hope this helps :)
(1/6)(36/100)<4 - (2/10)
6/100 < 38/10
3/50 < 190/50
