Which equation fits the word problem? Katie rented a bike from James' Bikes. It cost $19 plus $6 per hour. If Katie paid $49, then he rented the bike for how many hours?

Answers

Answer:

5 hours

Step-by-step explanation:

19+6=25 1

25+6=31 2

31+6=37 3

37+6=43 4

43+6=49 5

Answer:

5 hours

Step-by-step explanation:

49(total)-19(base charge) = 30(rented money needed). 6 times 5 = 30. So, Katie paid 5 hours. Kind of confusing but trust me. Hope this helps

Figure B

Answers

Yes, they are congruent. (congruent means they're the same shape and size!)

A rotation of 180 degrees should be a motion that maps A onto B. Or vice versa.

A MAN walked for 1/3 hour and then got an automobile ride for 1/2 hour. what part of time consumed he ride on automobile ????(a) 1/3
(b) 3/5
(c) 5/6

Answers

Walk - $(1)/(3) h$
Ride - $(1)/(2)h$
Journey took $(1)/(3)+(1)/(2) = (2+3)/(6) = (5)/(6) h$ = 50 minutes
and $(1)/(2)$ it's a $(3)/(5)$ of time

answer B

Final answer:

To find the part of time consumed riding the automobile, subtract the time spent walking from the total time. The correct answer is 5/9 hour.

Explanation:

To find the part of time consumed riding the automobile, we need to compare the time spent walking to the total time. The total time is 1/3 hour + 1/2 hour, which is equal to 5/6 hour. To find the part of time consumed riding, we subtract the time spent walking from the total time. So, the part of time consumed riding the automobile is 5/6 hour - 1/3 hour, which is equal to 10/18 hour. Simplifying this fraction, we get 5/9 hour. Therefore, the correct answer is (c) 5/9.
