Answer: It is asking the amount of pure water.
Amount of pure water evaporated is 64 gallons .
Step-by-step explanation:
Let x gallons be the amount of evaporated water.
Amount of water before evaporation
=12% of 160
= 0.12(160) = 19.2 gallons .......(1)
amount of solution after x gallon water evaporation = 160-x
amount of salt in 160-x solution = 20% of 160-x
=0.2 (160-x) ........... (2)
Since amount of salt will be same before and after evaporation
from (1 ) and (2)
0.2(160-x) = 19.2
32-0.2x = 19.2
-0.2x = 19.2-32
-0.2x = -12.8
x = -12.8/(-0.2)
x = 64 gallons
Answer:
y = -2x - 8
Step-by-step explanation:
<u>Use the point slope form: (y - y1) = m(x - x1)</u>
(y - (-4)) = -2(x - (-2))
y + 4 = -2(x + 2)
y + 4 - 4 = -2x - 4 - 4
y = -2x - 8
Answer: y = -2x - 8
