Answer:
Step-by-step explanation:
factors for
40=1,2,4,5,8,10,20,40
41=1,41 prime
3526=1,2,41,43,82,86,1763,3526
1001=1,7,11,13,77,91,143,1001
3+x=12
x=9
To solve this question, you can subtract 3 from 12 to get that Kathy started with 9 pens :)
Express s in terms of v and t
s= v/t, multiplying both sides of the equation by t
Express t in terms of v and s
t= s/v ( from s=vt)
