When you multiply/divide by a negative number while solving the inequality, you reverse the symbol.
A.) 4(5 - y) ≥ 80 To solve this, isolate/get the variable "y" by itself in the inequality. Divide 4 on both sides
5 - y ≥ 20 Subtract 5 on both sides
5 - 5 - y ≥ 20 - 5
-y ≥ 15 Divide -1 on both sides to get "y" by itself
Because you are dividing by a negative number, you need to reverse the sign
y ≤ -15
B.) 2(y - 3) ≥ 8 Isolate "y", divide 2 on both sides
y - 3 ≥ 4 Add 3 on both sides to get "y" by itself
y ≥ 7
C.) 3y - 4 > 1 Add 4 on both sides
3y > 1 Divide 3 on both sides to get "y" by itself
D.) 
Isolate "y", add 3/4 on both sides
6y > 1 Divide 6 on both sides to get "y" by itseld

Step-by-step explanation:
Often, all the mayflies in a population mature at once (a hatch), and for a day or two in the spring or autumn, mayflies are everywhere, dancing around each other in large groups, or resting on every available surface.
Answer:
a: The percentage change from 1/3 to 2/3 is 100 %
b: The percentage change from 1/3 to 1/6 is 0 %
Step-by-step explanation:
use this formula:
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((2/3 - 1/3) / 1/3) * 100 = 100 %
_________________________________
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((1/6 - 1/3) / 1/3) * 100 = 0 %
The answer will be 22 square ft. hope it helps
