Answer:
1) x= -2
2) x= 3
3) x=7
4) x>5
5) x=-14
Step-by-step explanation:
1) −3x − 3 −7x = 17
−10x−3=17
−10x=17+3
−10x=20
x= -20/10
x=-2
2) 10x − 6 = 24
10x=24+6
10x=30
x= 30/10
x= 3
3) −4−5x=−39
−5x=−39+4
−5x=−35
x=-35/-5
x= 7
4) 3x - 5 > 10
3x>10+5
3x>15
x>15/3
x>5
5) -5 + x + 16 = -3
x+11=−3
x=−3−11
x=-14

What is the question
Step-by-step explanation:
FINISH
Answer:
I'd say A is the correct answer. There's a chance I'm wrong but I don't think so
Recall your d = rt, distance = rate * time.
bearing in mind that, when she's going downstream, she's not going 40 mph, she's going 40 + 4 mph, because the stream is adding its speed to it.
likewise, when she's going upstream, she's going 40 - 4 mph, because the stream is eroding speed from it, thus

so, "u" is 16 minutes and 40 seconds.
and "d" is 13 minutes and about 38 seconds.
