<span><span>Let x = amt of water evaporated
.05(50) = .08(50-x)
2.5 = 4 - .08x
.08x = 4 - 2.5
.08x = 1.5
x =
x = 18.75 lb of water evaporated
Check; amt of salt remains the same, only the percentage is different, right?
.05(50) = .08(50-18.75)
.05(50) = .08(31.25)
2.5 = 2.5</span><span>

<u>It's between 300,000 and 400,000. </u>
<h2>The answer is 300,000 and 400,000. </h2>
Hope this helps! :)

D = rt
We are given the rate r to be 15 mph.
We are given the time (in hours) to be 3.5.
We need to find D.
D = (15)(3.5)
D = 52.5 miles.
Did you follow?
Answer:
Step-by-step explanation:
6) 15 + 2x = 75 Check: 15 + 2x = 75
2x = 75 - 15 15 + 2*30 = 75
2x = 60 15 + 60 = 75
x = 60/2 75 = 75
x = 30
7) m/3 - 14 = 10
m/3= 10 + 14
m/3 = 24
m = 24 *3
m = 72
