Answer:
N(c) = (C - 15)/20.
Step-by-step explanation:
C(n) = 20n + 15
20n = C- 15
N(c) = (C - 15)/20.
Answer: 4x4=16-7=9gallons
She will order 9 gallons
Step-by-step explanation:
Answer:
PERIMETER=Y+2Y+11+-3Y-9+Y^2+5Y-1+6Y^2
=7Y^2+4Y+1
P=12T
Q=66T
-----------
Toys added to each bag:
P=12T+nT
Q=66T+nT
Therefore, 66T+nT=3(12T+nT)
------------
66T+nT=36T+3nT
T(66+n)=T(36+3n)
66+n=36+3n
3n-n=66-36
2n=30
Therefore, n=30/2=15
-------------
*She added 15 toys to each bag.
