Question

if you count 40 wheels of tryicles and bycicles and tere are only 8 bikes, how many of them are trycicles

Answer 1

Hi Isabella S.,

There are 8 bicycles (bikes - 2 wheels) and unknown x tricycles (3 wheels) with a total of 40 wheels.

8*2 + x*3 = 40

16 + 3x = 40

16 + 3x = 40

-16 -16

3x = 24

÷3 ÷3

x = 8

So there are also 8 tricycles.

I hope this helps, Joe.

Answer 2

16 wheels come from the 8 bikes.

24 wheels come from the tricycles.

How many tricycles are there?
