Answer:
n = -4/5
Step-by-step explanation:
-3/4 n + 1/8 n= 1/2
use the rules of signs for multiplication
-3/4 n + 1/8 n= 1/2
multiply both sides 8
-6n + n = 4
collect like terms
-5n = 4
divide both sides by -5
n=-4/5
or alternative form
n=-0.8
Answer:
1140 ways.
Step-by-step explanation:
The applicable formula is: (n +r - 1)C(r-1), where n is the number of identical items (the candies), and r is the possible number of recipients (the kids).
The 17 identical candies, can be distributed among the 4 children in :
=(17 + 4 - 1)C(4–1) = 20C3 ways.
= 20!/((20–3)!*3!) ways.
= 20*19*18*17!/(17!*(3*2*1)) = 20*19*18/6 ways
= 20*19*3 ways.
=1140 ways.
