Answer:
180
Step-by-step explanation:
k = 3
v = 60
(Found v by dividing any of the top numbers by the bottom number, ex: 420/7 = 60)
3k = 3(60)
3k = 180

Answer:
  B 3x: 51  = 3x+24: 85
Step-by-step explanation:
Since the triangles are similar
PS             PQ
------- =  -----------
PT                PR
Substitute the values in
3x             3x+24
------- =  -----------
51         85
3x: 51  = 3x+24: 85
