Answer:
a)never b)always c)never d)sometimes.
Step-by-step explanation:
I’ll try to explain by giving examples for each:
a) let’s take n=-1 => 2*1/10= 2/10 =0,2 = > the number won’t be negative => answer:never.
b)let’s take q=-2 => (-2)*100000=-200000 => answer:always.
c)let’s take m=-2 => 6*1/100 = 6/100 =0,06; and 60^-2 = 1/60^2=1/360=0.02... => answer:never.
d)let’s take 1) p=1000; => 1000/1000=1. 2) p= 2 => less than 1. => answer:sometimes.
Okay so your equation is going to be : 18= 5k + 3.25p
we have 24 which has 1,2,3,4,6,8,12,24 as factors
1) 8p+3f=$10.39
2) 5p+4f=$10.51
where p represents pencil & f represents folder.
multiply the first equation by 5 and the second equation by 8.
40p+15f=$51.95
40p+32f=$84.08
Subtract
17f=$32.13
f=$32.13/17 =$1.89
Answer:
b
