Rate x time = distance
b = rate boat travels in still water
c = rate of the current
(b-c)4 = 216
(b+c)4 = 304
4b - 4c = 216
4b + 4c = 304
___________
8b = 520
b = 65 Km/hr
4c = 304 - 4b = 304 - 260 = 44
c = 11 Km/hr
Answer:
Answer : 5
Step-by-step explanation:
Step-by-step explanation:
- The first reason is given. Since the question gave us those, we say its given.
- The second/third reason is also given
- The fourth reason is alt int angles. A transversal crosses through parallel lines AB and DE.
- The fifth is definition of a midpoint.
- The final is SAS
Answer: Y = -2 and x = 1
Simplify:
10x − 4y = 18
3x + 4y = -5
Substitute and then the final answer is shown above.
Total exercise time answer is C
Total calories burned answer is B
The athlete spent 38 minutes on the rowing machines
