<span>Let x = amt of water evaporated :.05(50) = .08(50-x) 2.5 = 4 - .08x .08x = 4 - 2.5 .08x = 1.5 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>
Answer:
456
Step-by-step explanation:
thank you for the free ponits :)))
Let p positive number:
p²+44²>250250
p²>250250-44²
p²>248314
take the square root of both sides:
√p²>+√248314
p> 498.3 or 500 is the number
