Answer:
-1/36
Step-by-step explanation:
18=-1/(2k)
2k=-1/18
k=(-1/18)/2
k=(-1/18)(1/2)
k=-1/36
Answer:
asymptote
Step-by-step explanation:
Cost of flakes per ounce is $0.1204 ,
a. If a box cost $77.05 then approximately 640 pounds of flakes are in box.
b. Cost of 2-pound flakes is $3.8525.
As given,
Cost of flakes = $0.1204/ounce
a.
Cost of a box =$77.05
1 pound =16 ounces
$0.1204 =1 ounce
⇒$77.05 =77.05 /0.1204
= 639.95
≈ 640 ounces
= 40 pounds
b. Cost of 2 pounds =(77.05 /40)× 2
= $3.8525
Therefore, there are
a. Approximately 640 pounds of flakes are in box.
b. Cost of 2-pound potato flakes is $3.8525.

Problem 4:
multiply by 11,
8(n-10) = 64*11
divide by 8,
n-10 = 8*11
Add 10,
n = 88 + 10 = 98

Problem 5:
-0.6(r+0.2)=1.8
Divide by -0.6,
r+0.2 = -3
subtract 0.2,
r = -3 - 0.2 = -3.2

Problem 6:
I hope this method isn't too confusing for you,
but I would multiply through by the LCM of the denominators to get rid of the fractions. LCM of 3, 9 and 5 is 45.
Multiply both sides by 45,
(45w - 20)(-30) = -36
Divide -30,
45w - 20 = 36/30
Add 20,
45w = 36/30 + 20
Divide 45 as a final step,
w = 21.2/45
Then, the number must be greatest in the series.
