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:
Step-by-step explanation: It is 2/9 because 2/9 converts to 0.222222222...

The equation that does not justify the similarities of both triangles is:
<h3>Similar triangles</h3>
Similar triangles may or may not have congruent sides.
The triangles are given as:
The above means that, the following sides are similar
- Line segments PQ and ST
- Line segments QR and TR
- Line segments PR and SR
So, the equation that does not justify the similarities of both triangles is:

The value of 3 would be 3,000.
Why thousands? Well because u have to count from the right, then back, so ones, tens, hundreds, then thousands lands on 3 so hope this helps.
If sides are congruent then the angles ACROSS from them are also congruent.
Since WV and VU are congruent, angle U is congruent to angle W.
Set up an equation and solve.
See attachment.
x = 8
Angle w = 63
