x and y are the packs of organic and inorganic fertilizer, respectively.
pounds of nitrogen added = 2x + 6y = 120
pounds of potassium added = 3x + 2y = 54
eliminate the y terms. subtract the first equation from 3 times the second equation.
9x + 6y = 162
-2x - 6y = -120
------------------
7x = 42
x = 6
y = 18
R is the rate (10%)
C=20, begiing rate
T=time=8
so
h=20(1+0.10)^8
h=20(1.1)^8
h=42.8718

$42.87
D is answer
Answer:
37
Step-by-step explanation:
all triangle's angle measures add up to 180
180-98-45 = x
x = 37
Answer:
1.50
Step-by-step explanation:
Answer:
x/3= $12.85
Step-by-step explanation:
x/3= $12.85
multiply 3 on both sides to get x= $38.55
