x=15, y=-5. Please give brainliest and comment below if you need me to explain how i got this answer.
Answer:
- √3 / 3, 4th quadrant
Step-by-step explanation:
cot 5π/3 = cot 5 x 180° / 3 = cot 300° ( 4th quadrant)
cot 5π/3 = - √3 / 3
Answer:
t = 5
Step-by-step explanation:
Given
t + 2 = 7 ( isolate t by subtracting 2 from both sides )
t = 7 - 2 = 5
Answer:
The first one is correct
The second one is also correct
The third is also correct

<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>
