Answer:
a = 20 . . . . liters
Step-by-step explanation:
To solve this, multiply the equation by 30+a:
a = 0.4(30 +a)
a = 12 + 0.4a . . . . . eliminate parentheses
0.6a = 12 . . . . . . . . subtract 0.4a
a = 12/0.6 = 20 . . . divide by the coefficient of a
20 L of alfalfa must be added
_____
<em>Check</em>
20/(30+20) = 20/50 = 40/100 = 0.4 . . . . . . answer checks OK
Answer:
9, 10, 11, 12, and 13
Step-by-step explanation:
The first term is determined when n=1, therefore a(1)=1+8=9
The second term is determined when n=2, therefore a(2)=2+8=10
The third term is determined when n=3, therefore a(3)=3+8=11
The fourth term is determined when n=4, therefore a(4)=4+8=12
The fifth term is determined when n=5, therefore a(5)=5+8=13
