<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>

Answer:
3408
Step-by-step explanation:
you just need to plug 13 in for x and divide 3.25 by 11076.
Hope this helps.
Answer:
its the last one I think.
By setting both equations to zero and getting x alone you find your anwer
x-2=0 3x-2=0
+2 +2 +2 +2
x=2 3x=2
/3 /3
x=2/3
Answer:
y = (-2/5)x - 4
Step-by-step explanation:
y = mx + b
where m is the slope and b is the y-intercept
Therefore, y = (-2/5)x - 4
