Question

in the playground for kindergarten kids, 18 children are riding tricycles or bicycles. if there are 43 wheels in all, how many tricycles are there?

Answer 1

3T+2B=43 assuming no kids have trainng wheels on bicycles.

T+B=18 assume each bike and trike has only one kid on it.

3T+2(18-T)=43
T=43-36=7
check that.

Answer 2

The answer is 9. I put 3 into 43 9 times.

Answer 3

Bob showed you that T = 7, then B = 11
there are 7 trikes and 11 bikes

check: total is 18 vehicles
7(3) + 11(2)
= 21 + 22 = 43
Bob's answer is correct

Answer 4

1T and 20B

Answer 5

The solution is too simple.

Lets try to solve if the answer is 7 or 9.

9 tricycle x 3 (tricycle wheel) = 27 wheels
27 tricycle wheels - 43 wheels ( given in the question) = 16 wheels remaining
16 wheels / 2 (bicycle) = 8 bicycle

Which means, there's a possibility that this is the answer. Now, let's solve it using 7 tricycles.

7 tricycles x 3 (tricycle wheel) = 21 wheels of tricyles
21 wheels of trycicles - 43 wheels (given in the question) = 22 wheels
22 wheels / 2 (tricycle) = 11 bicycles

Now, it is also possible that this si the answer. BUT! we have to consider one thing and that is the 18 children on the questioni

If your answer is 9. Then,
= 9 tricycles + 8 bicycles = 17 (which means only 17 children can ride)

If your answer is 7. Then,
=7 trycicles + 11 bicycles = 18
(this is the correct answer because evey children in the park can ride)

Answer 6

Both of them is correct. But we have to choose the BEST ANSWER. 😅
