To answer this item, we let x and y be the rate of the boat in still water and current, respectively. The distance traveled by the object is equal to the product of the speed and the time.
Upstream:
D = (x + y)(6)
24 = 6x + 6y
4 = x + y
Downstream:
D = (x - y)(6)
18 = 6x - 6y
3 = x - y
The values of x and y are 3.5km/h and 0.5 km/h, respectively.
Answers:
Rate in Still water = 3.5 km/h
Rate of the current = 0.5 km/h
Answer:
True
Step-by-step explanation:
Since the rule is (x, y) ---> (x - 3, y - 4), you would subtract 3 from 0 (the x value of A) which would be -3. Then subtract 4 from 7 (the y value of A), which would be 3. So the answer would be true, that A' would be (-3, 3).
Answer:
Step-by-step explanation:
A. (b - 10)(b + 10) = 180
-100 = 180
= 280
b = 
b = 2
Your A is correct.
B. 2 - 10 = c
c = 6.733200531 = 6.73 Try rounding to 3 significant figures.
C. 2 + 10 = d
d = 26.73320053 = 26.7
You are correct in all 3 answers. Perhaps you should try rounding to 3 significant figures for your c and d values.
I hope this helps!! ^-^
Just add 2.5 + 13.5 (16) and multiply it my ten (160)
and i cant do it</h2>
